We investigate the low energy regime of BFSS quantum mechanics using its holographic dual. We identify three distinct thermodynamic phases (black holes) and analyze their thermodynamic properties extensively, including phase transitions amongst the several phases. While the properties of the canonical ensemble aligns with existing conjectures on BFSS thermodynamics, we uncover intriguing and unexpected

The phase diagram of the heavy fermion compound UTe2 contains multiple superconducting phases, several of which show characteristics of odd-parity pairing. We have investigated the pressure dependence of the superconducting transition in high-quality crystals of UTe2 by tracking its signature in the magnetic susceptibility χ(T). A single, sharp superconducting transition is observed at low pressures

Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-standard-model (BSM) interactions that couple electrons and neutrons. However, it is crucial to distinguish higher-order standard model (SM) effects from BSM physics. We measure the IS of the transitions P30→P31 in Ca14+ and S21/2→D5/22 in Ca+ with sub-Hz precision as well as the nuclear mass ratios with relative

Unlike in crystals, it is difficult to trace emergent material properties of amorphous solids to their underlying structure. Nevertheless, one can tune features of a disordered spring network, ranging from bulk elastic constants to specific allosteric responses, through highly precise alterations of the structure. This has been understood through the notion of independent bond-level response—the observation

Several small polycyclic aromatic hydrocarbons (PAHs) with closed-shell electronic structure have been identified in the cold, dark environment Taurus Molecular Cloud 1. We measure efficient radiative cooling through the combination of recurrent fluorescence (RF) and IR emission in the closed-shell indenyl cation (C9H7+), finding good agreement with a master equation model including molecular dynamics

Indentation tests are classical tools to determine material properties. For biological samples such as cysts of cells, however, the observed force-displacement relation cannot be expected to follow predictions for simple materials. Here, by solving the Pogorelov problem of a point force indenting an elastic shell for a purely nonlinear material, we discover that complex material behavior can even give

The current projected sensitivity on the electromagnetic coupling αem(mZ2) represents a bottleneck for the precision electroweak program at FCC-ee. We propose a novel methodology to extract this coupling directly from Z-pole data. By comparing the differential distribution of electrons, muons, and positrons in the forward region, the approach achieves a projected statistical sensitivity below the 10−5

I explore the limitations on the capacity of a relativistic channel to transmit power and information that arise because of the finiteness of the transverse speed of light. As a model system, I consider a rope constructed from a fundamental string, for which relativistic invariance is built in. By wiggling one end of the string, both power and information may be transmitted to the other end. I argue

Anomalous thermal relaxation is ubiquitous in nonequilibrium statistical mechanics. An emblematic example of this is the Mpemba effect, where an initially “hot” system cools faster than an initially “cooler” one. This effect has recently been studied in a variety of different classical and quantum settings. In this Letter, we find a novel signature of the Mpemba effect in the context of quantum batteries

Encoding quantum information via time-bin entangled states has had a profound impact on the development of quantum communications. However, dispersive propagation limits their achievable transmission distances. Here we describe a regime for nonlocal dispersion cancellation where the sum of arrival times of photons undergoing identical dispersion remains highly correlated. We exploit this effect to

Since its rediscovery in the twentieth century, the Mpemba effect, where a far-from-equilibrium state may relax faster than a state closer to equilibrium, has been extensively studied in classical systems and has recently received attention in quantum systems. Many theories explaining this counter-intuitive behavior in classical systems rely on memory effects. However, in quantum systems, the relation

We report on the utilization of Si in plasmonics research, specifically targeting deep ultraviolet (DUV) applications. By incorporating periodic submicron gratings on a Si surface, we demonstrate a photoconductive Si detector with significantly enhanced responsivity to DUV light, which is achieved via surface plasmon resonance (SPR). Notably, even without a metal, the detector exhibits improved responsivity

Altermagnets are collinear compensated magnets in which the magnetic sublattices are related by rotation rather than translation or inversion. One of the quintessential properties of altermagnets is the presence of split chiral magnon modes. Recently, such modes have been predicted in MnF2. Here, we report inelastic neutron scattering results on an MnF2 single crystal along high-symmetry Brillouin

We perform three-photon photoassociation to obtain high resolution spectra of Rb87 trilobite dimers for the principal quantum numbers n=22, 24, 25, 26, and 27. The large binding energy of the molecules in combination with a relative spectroscopic resolution of 10−4 provides a rigorous benchmark for existing theoretical models. A recently developed Green’s function framework, which circumvents the convergence

Neutrino telescopes, including IceCube, can detect galactic supernova events by observing the collective rise in photomultiplier count rates with a subsecond time resolution. Leveraging precise timing, we demonstrate for the first time the ability of neutrino telescopes to explore new weakly coupled states emitted from supernovae and subsequently decaying to neutrinos. Our approach utilizes publicly

I present a highly efficient integration method for scattering calculations, and a “partial rate matrix” that encodes the scattering rate as a function of the SO(3) orientation of the detector. This replaces the original multidimensional rate integral with a simple exercise in vector multiplication, speeding up the rate calculation by a factor of around 108. I include a scheme to fully factorize the

We show that collisions between particles free falling from infinity and a disk of material plunging off the retrograde innermost stable circular orbit of a near-extremal Kerr black hole is the unique astronomically natural way in which to create a gravitational particle accelerator with center of mass energies at the tens to hundreds of teraelectronvolt range; in other words, a supercollider. Published

When a column of water drains from a vertical tube, it often leaves behind a trailing film that forms intricate, axisymmetric liquid structures. Using high-speed imaging and first-principles modeling, we investigate the formation and breakup of these fluted films and demonstrate that their diverse morphologies arise from the evolving balance of inertia, surface tension, gravity, and viscous forces

We address the challenge of incorporating non-Markovian electronic friction effects in quantum-mechanical approximations of dynamical observables. A generalized Langevin equation is formulated for ring-polymer molecular dynamics rate calculations, which combines electronic friction with a description of nuclear quantum effects for adsorbates on metal surfaces. An efficient propagation algorithm is

We construct the first binary black hole solutions of Einstein-Maxwell theory in asymptotically anti–de Sitter space. The attractive force between the two black holes is balanced by the addition of a background electric field, sourced at the conformal boundary. There is a continuous family of bulk solutions for a given boundary profile and temperature, suggesting there is continuous nonuniqueness.

We propose a numerical method to estimate one-point functions and the free-energy density of conformal field theories at finite temperature by solving the Kubo-Martin-Schwinger condition for the two-point functions of identical scalars. We apply the method for the critical O(N) model for N=1, 2, 3 in 3≤d≤4. We find agreement with known results from Monte Carlo simulations and previous results for the

Collective oscillations in dense neutrino gases (flavor waves) are notable for their instabilities that cause fast flavor conversion. We develop a quantum theory of interacting neutrinos and flavor wave quanta, which are analogous to plasmons but also carry flavor. The emission or absorption of such flavor plasmons ψ, or “flavomons,” changes the neutrino flavor. When an angular crossing occurs, the

As analogues of compact objects, solitons have attracted significant attention. We reveal that cylindrical Q strings exhibit a dynamical instability to perturbations with wavelengths exceeding a threshold λ>λc. This instability can destroy the invariance in the cylindrical direction, as a generation mechanism for Q balls, similar to the formation of droplets. As the interface of Q strings approaches

We performed the longest numerical-relativity neutrino-radiation magnetohydrodynamics simulation for a binary neutron star merger that extends to ≈1.5s after the merger. We consider the binary model that undergoes the prompt collapse to a black hole after the merger with asymmetric mass 1.25M⊙ and 1.65M⊙ and SFHo equation of state. We find the Poynting flux-driven collimated outflow as well as the

To explain the baryon asymmetry in the early universe via leptogenesis, quantum corrections to new particles are commonly invoked to generate the necessary CP asymmetry. We demonstrate, however, that a large CP asymmetry can already arise from standard model leptons. The mechanism relies on resummation of soft leptons at finite temperatures. The CP asymmetry, which is kinematically forbidden in vacuum

Ultralight dark photons are compelling dark matter candidates, but their allowed kinetic mixing with the standard model photon is severely constrained by requiring that the dark photons do not collapse into a cosmic string network in the early Universe. Direct detection in minimal production scenarios for dark photon dark matter is strongly limited, if not entirely excluded; discovery of sub-meV dark

We singled out the surface and bulk spin dynamics in magnetic hollow nanoparticles by means of nuclear magnetic resonance relaxometry. Experimental H1−NMR-dispersion curves (NMR-D), measured across a wide frequency range (104 Hz

It is still an open question if magnetoelectric coupling occurs at the atomic scale in multiferroic BiFeO3. Nuclear solid-state techniques monitor local fields at the atomic scale. Using such an approach, we show that, contrary to our own expectation, ferroelectric and magnetic ordering in bismuth ferrite (BiFeO3 or BFO) decouple at the unit-cell level. Time differential perturbed angular correlation

We present a full Batalin-Vilkovisky action in the component field formalism for N=1 supergravity in ten dimensions coupled to Yang-Mills multiplets. Published by the American Physical Society 2025

A major limitation of laser interferometers using continuous wave lasers are parasitic light fields, such as ghost beams, scattered or stray light, that can cause nonlinear noise. This is especially relevant for laser interferometric ground-based gravitational wave detectors. Increasing their sensitivity, particularly at frequencies below 10 Hz, is threatened by the influence of parasitic photons.

The stretching response of polymer chains fundamentally determines the mechanical properties of polymer networks. In this Letter, we develop a statistical mechanics model that incorporates both bond stretching and bond angle deformation, enabling accurate predictions of chain behavior up to large forces. We further propose a semianalytical deformable freely rotating chain (dFRC) model, which represents

We report a proof-of-principle experiment for a new method of temperature measurements in waveguide quantum electrodynamics experiments, allowing one to measure separately the temperature of global and local baths. The method takes advantage of collective states of two transmons located in the center of a waveguide. The Hilbert space of such a system forms two separate subspaces (bright and dark) that

Ever since the advent of quantum mechanics, tunneling has been an intriguing topic and consequently extensively studied and utilized. Investigating both theoretically and experimentally the nonadiabatic tunneling in strong-field ionization across a wide range of laser intensities, we unravel under-the-barrier-recollision dynamics leading to Freeman resonances (FR). The under-the-barrier-recollision

The recent breakthroughs regarding the detection of compact binary mergers via gravitational waves opened up a new window to the Universe. Gravitational-wave models have been essential to this success since they are necessary to infer the properties of the compact binary system from the observational data. Next-generation detectors, such as the Einstein Telescope, will allow for more observations of

Polarons are crucial for charge transport in semiconductors, significantly impacting material properties and device performance. The dynamics of small polarons can be investigated using first-principles molecular dynamics. However, the limited timescale of these simulations presents a challenge for adequately sampling infrequent polaron hopping events. Here, we introduce a message-passing neural network

We report an extensive high-field study of atacamite Cu2Cl(OH)3, a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed magnetic fields up to 58 T. In particular, we have mapped the entropy landscape for fields as high as 35 T and have identified a field-induced quantum critical point at 21.9(1) T for H∥c axis. The quantum critical point separates

The type IIB matrix model is conjectured to describe superstring theory nonperturbatively in terms of ten N×N bosonic traceless Hermitian matrices Aμ (μ=0,…,9), whose eigenvalues correspond to (9+1)-dimensional space-time. Quite often, this model has been investigated in its Euclidean version, which is well defined although the SO(9,1) Lorentz symmetry of the original model is replaced by the SO(10)

We present the first amplitude analysis and branching fraction measurement of the decay D_{s}^{+}→π^{+}π^{+}π^{-}π^{0}π^{0}, using e^{+}e^{-} collision data collected with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV corresponding to an integrated luminosity of 7.33  fb^{-1}, and report the first observation of the pure W-annihilation decay D_{s}^{+}→ωρ^{+} with a branching

The nonlinear response of yield stress fluids remains difficult to predict and control. Here, we show that the height of the overshoot in the loss modulus G^{''}, a key characteristic of yielding, depends only on linear viscoelastic properties. Furthermore, the position of this overshoot depends on linear viscoelastic and flow properties, demonstrating the important and enduring role of elasticity

We present the first measurement of cosmic-ray fluxes of ^{6} Li and ^{7} Li isotopes in the rigidity range from 1.9 to 25 GV. The measurements are based on 9.7×10^{5} ^{6} Li and 1.04×10^{6} ^{7} Li nuclei collected by the Alpha Magnetic Spectrometer on the International Space Station from May 2011 to October 2023. We observe that over the entire rigidity range the ^{6} Li and ^{7} Li fluxes exhibit

Non-Fermi liquid (non-FL) phase is a pivotal enigma in understanding intriguing quantum phases in strongly correlated systems, such as high-temperature superconductivity. Tomonaga-Luttinger liquid (TLL) theory, designed for one-dimensional (1D) systems, serves as one of the microscopic frameworks that elucidates non-FL behavior. Despite its theoretical concreteness, comprehensive experimental verification

The emergence of hydrodynamic behavior in electronic flow within clean, particle-hole-symmetric systems at half filling is a nontrivial problem. Navier-Stokes (NS) equations describe the momentum flow, while experimental measurements typically capture the current flow profiles. However, in particle-hole-symmetric systems, electric current and momentum flow are entirely decoupled, because electrons

We report new constraints on axionlike particles (ALPs) using data from the NEON experiment, which features 16.7 kg of NaI(Tl) target located 23.7 m from a 2.8 GW thermal power nuclear reactor. Analyzing a total exposure of 3063  kg·day, with 1596  kg·day during reactor-on and 1467  kg·day during reactor-off periods, we compared energy spectra to search for ALP-induced signals. No significant signal

Superconductivity usually emerges from a metallic normal state which follows the Fermi-liquid paradigm. If, in contrast, the normal state is a fractionalized non-Fermi liquid, then pairing may either eliminate fractionalization via a Higgs-type mechanism leading to a conventional superconducting state, or pairing can occur in the presence of fractionalization. Here, we discuss a simple model for the

Silicate melts not only govern key processes in the Earth's early evolution, but also significantly influence its interior dynamics today. MgSiO_{3}, a primary component of silicate melts, undergoes significant structural changes and exhibits complex macroscopic properties from the Earth's surface to the core-mantle boundary. Despite extensive studies, the atomic structure, densification mechanisms

We study the self-organization of turbulence in a geophysically motivated two-dimensional fluid with local interactions. Using simulations and theory, we show that the out-of-equilibrium flux to small scales imposes a constraint on the large-scale emergent flow. Consequently, a rich phase diagram of large-scale configurations emerges, replacing the unique state found in flows with energy injection

Valley photonics, with its rapid advancements and immense potential, lays one pivotal cornerstone toward next-generation topological photonic devices. It enables valley-polarized topological states, whose valleys are intrinsically locked up with transmission directivity. However, these states are prone to defects in photonic structures, and backscattering may easily induce valley flipping. Hence, achieving

Metal-containing molecular ions are fundamentally important in both terrestrial and interstellar chemistry, yet their formation mechanisms have been largely unexplored experimentally. To address this lack of fundamental understanding of how these ions are created in space, we conducted an experimental study of a quantum-state-controlled reaction between Ca^{+} and C_{2}H_{2} to investigate a potential

In quantum error correction, the Petz map serves as a perfect recovery map when the Knill-Laflamme conditions are satisfied. Notably, while perfect recovery is generally infeasible for most quantum channels of finite dimension, the Petz map remains a versatile tool with near-optimal performance in recovering quantum states. This work introduces and proves, for the first time, the necessary and sufficient

Bound states in the continuum (BICs) are exceptional resonances with extremely high sensitivity and thus inherently fragile. Introducing topological concepts can fortify BICs against perturbations; however, existing topological BICs (TBICs) often rely on intricate strategies. Here, we explore the universality of TBICs governed by symmetry. Different symmetries naturally segregate wave states into uncoupled

The equation of state of quantum chromodynamics with Nf=3 flavors is determined nonperturbatively in the range of temperatures between 3 and 165 GeV with a precision of about 0.5%–1.0%. The calculation is carried out by numerical simulations of lattice gauge theory discretized Wilson with shifted boundary conditions in the compact direction. At each given temperature the entropy density is computed

We present a derivation and experimental implementation of a dimension-dependent contextuality inequality to certify both the quantumness and dimensionality of a given system. Existing methods for certification of the dimension of a quantum system can be cheated by using larger classical systems, creating a potential loophole in these benchmarks, or can in practice only be evaluated assuming pure quantum

We study the 1D Ising model with long-range interactions decaying as 1/r1+s. The critical model corresponds to a family of 1D conformal field theories whose data depend nontrivially on s in the range 1/2≤s≤1. The model is known to be described by a generalized free field with quartic interaction, which is weakly coupled near s=1/2 but strongly coupled near the short-range crossover at s=1. We propose

We study the directed transport of bosons along a one dimensional lattice in a dissipative setting, where the hopping is only facilitated by coupling to a Markovian reservoir. By combining numerical simulations with a field-theoretic analysis, we investigate the current fluctuations for this process and determine its asymptotic behavior. These findings demonstrate that dissipative bosonic transport

Bell nonlocality is a fundamental phenomenon of quantum physics as well as an essential resource for various tasks in quantum information processing. It is known that for the observation of nonlocality the measurements on a quantum system have to be incompatible, but the question of which incompatible measurements are useful, remained open. Here we prove that any set of incompatible measurements on

The exploitation of certification tools by end users represents a fundamental aspect of the development of quantum technologies as the hardware scales up beyond the regime of classical simulability. Certifying quantum networks becomes even more crucial when the privacy of their users is exposed to malicious quantum nodes or servers as in the case of multiclient distributed blind quantum computing,

We calculate the four-graviton scattering amplitude in Type II superstring theory at one loop up to seventh order in the low-energy expansion through the recently developed iterated integral formalism of Modular Graph Functions (MGFs). The machinery of the novel method allows us to propose a general form of the amplitude, which suggests that the expansion is expressible in terms of single-valued multiple

Identifying conservation laws is central to every subfield of physics, as they illuminate the underlying symmetries and fundamental principles. A prime example can be found in quantum optics: the conservation of orbital angular momentum (OAM) during spontaneous parametric down-conversion (SPDC) enables the generation of a photon pair with entangled OAM. In this Letter, we report on the observation

We propose a quantum measurement that probabilistically projects a pair of qudits of dimension d onto a Bell state in a two-qubit subspace. It can be implemented using linear-optical circuits with the success probabilities of 1−d−1 without ancilla photons and 1−d−(k+1) with 2(2k−1) ancilla photons. It allows us to entangle two independently prepared high-dimensional entangled states two dimensionally

A precise evaluation of the electroweak contribution to the anomalous magnetic moment of the muon requires control over all aspects of the standard model, ranging from Higgs physics, over multiloop computations for bosonic and (heavy-)fermion diagrams, to nonperturbative effects in the presence of light quarks. Currently, the dominant uncertainties arise from such hadronic effects in the vector–vector–axial-vector
