Mesoscopic Theory for Coupled Stochastic Oscillators Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-16 Victor Buendía
The celebrated Ott-Antonsen for coupled oscillators provides a useful framework for working with deterministic systems in the thermodynamic limit, but it fails to capture many features of stochastic systems. Several solutions have been recently proposed to accurately describe the behavior of the order parameters in coupled oscillator systems. However, a fluctuating description of such order parameters

Massive scalar fields are promising candidates for addressing many unresolved problems in fundamental physics. We report the first model-agnostic Bayesian search of massive scalar fields that are nonminimally coupled to gravity in LIGO/Virgo/KAGRA gravitational-wave data. We find no evidence for such fields and place the most stringent upper limits on their coupling for scalar masses ≲2×10−12eV. We

We have measured the critical current density, superconducting coherence length, and superconducting transition temperature of single-domain, epitaxially grown Nb(110)/Au(111)/Nb(110) trilayers, all of which show a nonmonotonic dependence on the thickness of the Au layer. These results are compared with the predictions of a relativistic, theory, which incorporates superconducting correlations. We find

Through laser-heated diamond anvil cell experiments, we synthesize a series of rubidium superhydrides and explore their properties with synchrotron x-ray powder diffraction and Raman spectroscopy measurements, combined with density functional theory calculations. Upon heating rubidium monohydride embedded in H2 at a pressure of 18 GPa, we form RbH9−I, which is stable upon decompression down to 8.7

We investigated the infrared-active phonons in ferromagnetic Weyl semimetal Co3Sn2S2 using optical spectroscopy. Below the Curie temperature (TC≈175 K), we observed asymmetric Fano line shapes of phonons peaks in the optical conductivities, reflecting the presence of electron-phonon coupling. Additionally, the detected phonon signals by the polar Kerr rotation and the ellipticity spectroscopy indicate

Weak Ferromagnetism in Altermagnets from Alternating g -Tensor Anisotropy Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-16 Daegeun Jo, Dongwook Go, Yuriy Mokrousov, Peter M. Oppeneer, Sang-Wook Cheong, Hyun-Woo Lee
Altermagnets are magnetic materials with antiferromagnetic spin ordering but exhibit ferromagnetic properties. Understanding the microscopic origin of the latter is a central problem. Ferromagnetlike properties such as the anomalous Hall effect are linked with weak ferromagnetism, whose microscopic origin in altermagnets remains unclear however. We show theoretically that the alternating g-tensor anisotropy

We present the high-precision result for the zero-jettiness soft function at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. At this perturbative order, the soft function is the last missing ingredient required for the computation of a hadronic color singlet production or a color singlet decay into two jets using the zero-jettiness variable as the slicing parameter. Furthermore, the

Ultracritical Floquet Non-Fermi Liquid Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-15 Li-kun Shi, Oles Matsyshyn, Justin C. W. Song, Inti Sodemann Villadiego
We demonstrate that periodically driven Fermions coupled to simple bosonic baths have steady state occupations of Floquet Bloch bands that generically display nonanalyticities at certain momenta that resemble the Fermi surfaces of equilibrium non-Fermi liquids. Remarkably these nonequilibrium Fermi surfaces remain sharp even when the bath is at finite temperature, leading to critical power-law decaying

Isospectrality in Effective Field Theory Extensions of General Relativity Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-15 Pablo A. Cano, Marina David
Two universal predictions of general relativity are the propagation of gravitational waves of large momentum along null geodesics and the isospectrality of quasinormal modes in many families of black holes. In extensions of general relativity, these properties are typically lost: quasinormal modes are no longer isospectral and gravitational wave propagation is no longer geodesic and it exhibits bi

We present an explicit construction of a relativistic quantum computing architecture using a variational quantum circuit approach that is shown to allow for universal quantum computing. The variational quantum circuit consists of tunable single-qubit rotations and entangling gates that are implemented successively. The single-qubit rotations are parameterized by the proper time intervals of the qubits’

We present a novel candidate for cold dark matter consisting of condensed Cooper pairs in a theory of interacting fermions with broken chiral symmetry. Establishing the thermal history from the early radiation era to the present, the fermions are shown to behave like standard radiation at high temperatures, but then experience a critical era decaying faster than radiation, akin to freeze-out, which

Beyond Electric-Dipole Treatment of Light-Matter Interactions in Materials: Nondipole Harmonic Generation in Bulk Si Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-13 Simon Vendelbo Bylling Jensen, Nicolas Tancogne-Dejean, Angel Rubio, Lars Bojer Madsen
A beyond electric-dipole light-matter theory is needed to describe emerging x-ray and THz applications for characterization and control of quantum materials but inaccessible as nondipole lattice-aperiodic terms impede on the use of Bloch’s theorem. To circumvent this, we derive a formalism that captures dominant nondipole effects in intense electromagnetic fields while conserving lattice translational

We propose a universal framework for classifying quantum states based on their scale-resolved correlation structure. Using the recently introduced information lattice, which provides an operational definition of the total amount of correlations at each scale, we define intrinsic characteristic length scales of quantum states. We analyze ground and midspectrum eigenstates of the disordered interacting

We construct a (1+1)d gapless theory which has Haagerup H3 symmetry. The construction relies on the recent exploration of the categorical Landau paradigm applied to fusion category symmetries. First, using the symmetry topological field theory, we construct all gapped phases with Haagerup symmetry. Extending this construction to gapless phases, we study the second order phase transition between gapped

Dilatonic Couplings and the Relic Abundance of Ultralight Dark Matter Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-13 Ahmad Alachkar, Malcolm Fairbairn, David J. E. Marsh
Models of scalar field dark matter where the scalar is a dilaton have a special behavior, since nontrivial couplings, d, to matter result in a contribution to the potential for the field that is proportional to the trace of the stress-energy tensor. We look in more detail at the dilaton mass, mϕ, and initial conditions required to yield the correct relic abundance for couplings that are not already

I Extremization with Baryonic Charges Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-12 Seyed Morteza Hosseini, Alberto Zaffaroni
We propose an entropy function for AdS4 BPS black holes in M theory with general magnetic charges, resolving in particular a long-standing puzzle about baryonic charges. The entropy function is constructed from a gravitational block defined solely in terms of topological data of the internal manifold. We show that the entropy of twisted black holes can always be reformulated as an I-extremization problem—even

An intercombination transition in Yb enables a novel approach for rapidly imaging magnetic field variations with excellent spatial and temporal resolution and accuracy. This quantum imaging magnetometer reveals “dark stripes” that are contours of constant magnetic field visible by eye or capturable by standard cameras. These dark lines result from a combination of Autler-Townes splitting and the spatial

The diversity of diffusive systems exhibiting long-range correlations characterized by a stochastically varying Hurst exponent calls for a generic multifractional model. We present a simple, analytically tractable model which fills the gap between mathematical formulations of multifractional Brownian motion and empirical studies. In our model, called telegraphic multifractional Brownian motion, the

Long baseline diffraction-limited optical aperture synthesis technology by interferometry plays an important role in scientific study and practical application. In contrast to amplitude (phase) interferometry, intensity interferometry—which exploits the second-order coherence of thermal light—is robust against atmospheric turbulence and optical defects. However, a thermal light source typically has

Continuous-Variable Square-Ladder Cluster States in a Microwave Frequency Comb Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-09 Fabio Lingua, J. C. Rivera Hernández, Michele Cortinovis, David B. Haviland
We describe an experiment demonstrating the generation of three independent square-ladder continuous-variable cluster states with up to 94 qumodes of a microwave frequency comb. This entanglement structure at a large scale is realized by injecting vacuum fluctuations into a Josephson Parametric Amplifier pumped by three coherent signals around twice its resonance frequency, each having a particular

He4 nanodroplets doped with an alkali ion feature a snowball of crystallized layers surrounded by superfluid helium. For large droplets, we predict that a transitional supersolid layer can form, bridging between the solid core and the liquid bulk, where the He4 density displays modulations of icosahedral group symmetry. To identify the different phases, we combine density functional theory with the

Diffusive Hydrodynamics from Long-Range Correlations Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-09 Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis, Benjamin Doyon
In the hydrodynamic theory, the nonequilibrium dynamics of a many-body system is approximated, at large scales of space and time, by irreversible relaxation to local entropy maximization. This results in a convective equation corrected by viscous or diffusive terms in a gradient expansion, such as the Navier-Stokes equations. Diffusive terms are evaluated using the Kubo formula, and possibly arising

Formation of Topological Bigels in Mixtures of Colloidal Rings and Polymers Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-09 Andrea Bonato, Davide Marenduzzo, Enzo Orlandini
We study a spherically confined mixture of polymers and colloidal rings. Unlike in standard colloid-polymer mixtures, the polymers interact topologically with the rings by threading them. We find that, above a critical value of the ring radius, threading yields a topological transition from a fluid to a gel-like phase characterized by a space-spanning network of interlocked polymers and rings, which

Enabling Strong Neutrino Self-Interaction with an Unparticle Mediator Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-08 Saeid Foroughi-Abari, Kevin J. Kelly, Mudit Rai, Yue Zhang
Recent explorations of the cosmic microwave background and the large-scale structure of the universe have indicated a preference for sizable neutrino self-interactions, much stronger than what the standard model offers. When interpreted in the context of simple particle-physics models with a light, neutrinophilic scalar mediator, some of the hints are already in tension with the combination of terrestrial

We measure the noise correlations of two-dimensional (2D) Bose gases after free expansion and use them to characterize the phase coherence across the Berezinskii-Kosterlitz-Thouless (BKT) transition. The noise correlation function features a characteristic spatial oscillatory behavior in the superfluid phase, which gives direct access to the superfluid exponent. This oscillatory behavior vanishes above

Nuclear charge radii of neutron-rich Sc47–49 isotopes were measured using collinear laser spectroscopy at CERN-ISOLDE. The new data reveal that the charge radii of scandium isotopes exhibit a distinct trend between N=20 and N=28, with Sc41 and Sc49 isotopes having similar values, mirroring the closeness of the charge radii of Ca40 and Ca48. Theoretical models that successfully interpret the radii of

We study the deformation of a liquid interface with arbitrary principal curvatures by a flat circular sheet. Working first at small slopes, we determine the shape of the sheet analytically in the membrane limit, where the sheet is inextensible yet free to bend and compress. We find that the sheet takes a cylindrical shape on interfaces with negative Gaussian curvature. On interfaces with positive Gaussian

Low-energy dynamics of QCD can be described by pion degrees of freedom in terms of the chiral perturbation theory. A chiral soliton lattice, an array of solitons, is the ground state due to the chiral anomaly in the presence of a magnetic field larger than a certain critical value at finite density. Here, we show in a model-independent and fully analytic manner (at the leading order of the chiral perturbation

Soft materials are ubiquitous in technological applications that require deformability, for instance, in flexible, water-repellent coatings. However, the wetting properties of prestrained soft materials are only beginning to be explored. Here we study the sliding dynamics of droplets on prestrained soft silicone gels, both in tension and in compression. Intriguingly, in compression we find a nonmonotonic

Discovering Electroweak Interacting Dark Matter at Muon Colliders Using Soft Tracks Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-05-06 Rodolfo Capdevilla, Federico Meloni, Jose Zurita
Minimal dark matter models feature one neutral particle that serves as a thermal relic dark matter candidate, as well as quasidegenerate charged states with TeV masses. When the charged states are produced at colliders, they can decay into dark matter and a low-momentum (soft) charged particle, which is challenging to reconstruct at hadron colliders. We demonstrate that a 3 TeV muon collider is capable

We present a new gauging of maximal supergravity in five spacetime dimensions with gauge group containing ISO(5), involving the local scaling symmetry of the metric, and admitting a supersymmetric anti–de Sitter vacuum.

We study dynamical gravitational collapse in a theory with an infinite tower of higher-derivative corrections to the Einstein-Hilbert action and we show that, under very general conditions, it leads to the formation of regular black holes. Our results are facilitated by the use of a class of theories that possess second-order equations on spherically symmetric metrics, but which are general enough

The search for axions sits at the intersection of solving critical problems in fundamental physics, including the strong CP problem in QCD, uncovering the nature of dark matter, and understanding the origin of the Universe’s matter-antimatter asymmetry. The measurement of axion mediated spin-dependent interactions offers a powerful approach for axion detection. However, it has long been restricted

A magnetically levitated mass couples to gravity and can act as an effective gravitational wave detector. We show that a superconducting sphere levitated in a quadrupolar magnetic field, when excited by a gravitational wave, will produce magnetic field fluctuations that can be read out using a flux tunable microwave resonator. With a readout operating at the standard quantum limit, such a system could

Axions and other putative feebly interacting particles with a mass of tens to several hundreds of keVs can be produced in stellar cores with a Lorentz boost factor Ea/ma≲10. Thus, starburst galaxies such as M82 are efficient factories of slow axions. Their decay a→γγ would produce a large flux of x-ray photons, peaking around 100 keV and spread around the Galaxy by an angle that can be relatively large

Quantum fluctuations in QCD influence nucleon structure and interactions, with pion production serving as a key probe of chiral dynamics. In this Letter, we present a lattice QCD calculation of multipole amplitudes at threshold, related to both pion electroproduction and weak production from a nucleon, using two gauge ensembles near the physical pion mass.

We study the superradiant decay of a chain of atoms coupled to a chiral waveguide, focusing on the regime of non-negligible photon propagation time. Using an exact master equation description that accounts for delay effects, we obtain evidence to suggest that competition between collective decay and retardation leads to the emergence of an effective maximum number of atoms able to contribute to the

Heavy-Flavor Angular Correlations as a Direct Probe of the Glasma Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-29 Dana Avramescu, Vincenzo Greco, Tuomas Lappi, Heikki Mäntysaari, David Müller
We use classical equations of motion for heavy quarks to show that the preequilibrium glasma phase of a heavy ion collision has an extremely strong effect on heavy quark angular correlations. At the same time the effect on the single inclusive spectrum is much more moderate. This suggests that DD¯ meson angular correlations in future LHC measurements could provide a direct experimental access to the

It has been a long-standing challenge to define a canonical loop integrand for nonsupersymmetric gluon scattering amplitudes in the planar limit. Naive integrands are inflicted with 1/0 ambiguities associated with tadpoles and massless external bubbles, which destroy integrand-level gauge invariance as well as consistent on-shell factorization on single loop cuts. In this Letter, we show that this

A targeted experiment at the National Ignition Facility (NIF) confirms the presence of multispecies hydrodynamics in inertial confinement fusion hohlraums relevant to ignition. The effects are identified by filling the gold hohlraum with a deuterium-tritium (DT) gas mixture instead of helium. As the hohlraum is heated by the NIF lasers, it implodes inward, compressing and heating the DT, which leads

Charged domain walls (CDWs) in ferroelectrics are often characterized as excited states, even after full bound charge compensation at domain walls (DWs). Here, we propose a mechanism where negative gradient energy (E_{grad}) counteracts the large positive electrostatic energy (E_{el}) induced by bound charge at DWs, stabilizing the CDWs over the bulk state, even with partial or no bound charge compensation

Quantum Thermodynamic Integrability for Canonical and Noncanonical Statistics. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 R X Zhai,C P Sun
We extend the Carathéodory principle of the second law to quantum thermodynamics, where energy levels depend on macroscopic variables such as volume and magnetic field. This extension introduces the concept of quantum thermodynamic integrability (QTI), providing an alternative foundation for statistical mechanics. QTI is characterized by the path independence of work and heat within the thermodynamic

Search for Solar Boosted Dark Matter Particles at the PandaX-4T Experiment. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 Guofang Shen,Zihao Bo,Wei Chen,Xun Chen,Yunhua Chen,Zhaokan Cheng,Xiangyi Cui,Yingjie Fan,Deqing Fang,Zhixing Gao,Lisheng Geng,Karl Giboni,Xunan Guo,Xuyuan Guo,Zichao Guo,Chencheng Han,Ke Han,Changda He,Jinrong He,Di Huang,Houqi Huang,Junting Huang,Ruquan Hou,Yu Hou,Xiangdong Ji,Xiangpan Ji,Yonglin Ju,Chenxiang Li,Jiafu Li,Mingchuan Li,Shuaijie Li,Tao Li,Zhiyuan Li,Qing Lin,Jianglai Liu,Congcong Lu
We present a novel constraint on light dark matter utilizing 1.54 metric ton/year of data acquired from the PandaX-4T dual-phase xenon time projection chamber. This constraint is derived through detecting electronic recoil signals resulting from the interaction with solar-enhanced dark matter flux. Low-mass dark matter particles, lighter than a few MeV/c^{2}, can scatter with the thermal electrons

Full-Scaling Friction and Wear Laws of Nanotwinned Metals. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 Yan Lin,Ziyue Zhang,Fenghui Duan,Fangming Wang,Fei Liang,Qicheng Zhang,Yong Li,Jie Pan,Keke Chang,Yonghao Zhao,Yuntian Zhu,Xiang Chen
Ultrastrong nanotwinned (NT) metals hold promise for mitigating friction and wear-essential for enhancing the energy efficiency and longevity of all moving systems. However, optimizing their tribological performance has long suffered from the absence of friction and wear laws across varying tribological loading scales. Here, we have discovered full-scaling twin lamella spacing (λ)-dependent friction

Ion Acoustic Instability Resulting from Suprathermal Electrons Generated by Stimulated Raman Scattering in Laser-Plasma Interactions. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 C Rousseaux,S D Baton,K Glize,L Lancia,D Bénisti,G Sary,L Gremillet
Using space-time-resolved Thomson scattering, we investigate experimentally the development of electrostatic waves in a preformed undercritical helium plasma driven by a 1.059 μm laser pulse of ∼1.5 ps duration and ∼10^{15-16} W cm^{-2} mean intensity. We observe the excitation of intense ion plasma waves (IAWs) over a broad wave number range, distinct from what is expected from stimulated Brillouin

Refractive Contribution to the Mass of an Elementary Excitation in a Dilute Bose-Einstein Condensate. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 S V Andreev
Since the pioneering works of Landau and Feynman, the origin of a roton minimum in the excitation spectrum of a quantum Bose liquid has been debated. A consensus has been reached on relation of the roton to eventual solidification, but this viewpoint still remains to be connected to the polaronic concept of an impurity pushing through a dense medium. The diagrammatic theory allows one to approach the

Differential Elasticity Affects Lineage Segregation of Embryonic Stem Cells. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 Christine M Ritter,Tianxiang Ma,Natascha Leijnse,Younes Farhangi Barooji,William Hamilton,Joshua M Brickman,Amin Doostmohammadi,Lene B Oddershede
The question of what guides lineage segregation is central to development, where cellular differentiation leads to segregated cell populations destined for specialized functions. Here, using optical tweezers measurements of mouse embryonic stem cells, we reveal a mechanical mechanism based on differential elasticity in the second lineage segregation of the embryonic inner cell mass into epiblast (EPI)

Surfactant Exchanges between Deformed Soap Films. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 Théo Lenavetier,Emmanuel Schaub,Isabelle Cantat
The effective viscosity of liquid foams is controlled by Marangoni forces and therefore by the transport of surfactants. Direct tracking of the latter during foam deformation is out of reach. Besides, the competition between diffusion and convection on the interfaces and in the bulk of complex assemblies of thin films and menisci is still an open problem. These shortcomings severely limit our understanding

Moiré Kramers-Weyl Fermions with Ideal Radial Spin Texture from Structural Chirality. Phys. Rev. Lett. (IF 8.1) Pub Date : 2025-04-25 D J P de Sousa,Seungjun Lee,Tony Low
We demonstrate that two-dimensional Kramers-Weyl fermions can be engineered in spin-orbit coupled twisted bilayers, where the chiral structure of these moiré systems breaks all mirror symmetries, confining Kramers-Weyl fermions to high-symmetry points in the Brillouin zone under time reversal symmetry. Our theoretical analysis reveals a symmetry-enforced, Weyl-like spinful interlayer moiré coupling
