We study the baryonic fluctuations from second to eighth order involving electric charge, baryon number and strangeness below the quark-gluon plasma crossover and numerically known from lattice QCD calculations. By considering a particular realization of the Hadron Resonance Gas model, we provide evidence on the dominant role of quark-diquark degrees of freedom to describe excited baryonic resonances

Neutron irradiation induces a large number of vacancies and self-interstitial atoms (SIAs) that interact with hydrogen atoms (H) and degrade the mechanical properties of tungsten (W) in a fusion environment. Vacancies increase free space and trap H atoms, however, the effects of SIAs on trapping H atoms are still unclear since SIAs decrease free space. We therefore perform systematical ab initio calculations

The imaging processing technique was used for studying a laser beam nature that transmitted through films of PM-355. The thermal nonlinearity of PM-355 films was studied using a 635 nm cw diode laser at 15 mW as the source of excitation. Third order nonlinear optical properties of PM-355 films irradiated with α -particles at different times and pristine sample has been studied using Z-scan technique

Muons in the final state represent an important signature for many physics studies performed at the Large Hadron Collider (LHC), involving analyses on Standard Model measurements and on new physics searches.

HiSPARC is an extensive network of cosmic ray detection stations mainly across The Netherlands and United Kingdom. Its primary goal is to analyse cosmic ray air showers by sampling their footprints using multiple detectors. Also the detection rates per single detector are recorded. These 'singles rates’ fluctuate in time. Large fluctuations are caused by precipitation. During rain an excess of 222

Liquid argon TPC (LAr-TPC) is an ideal detection technology for neutrino physics, combining excellent 3D spatial reconstruction and calorimetry. The ICARUS-T600 detector is the first large scale detector of this typology and its operation with the CNGS neutrino beam proved the maturity of the technique, while providing important results in sterile neutrino searches. A verification of the existence

The spontaneous fission fragments mass yield of 238 U is calculated with two models: WKB approximation model and statistical scission-point model. The results are compared with experimental data. This shows that the statistical scission-point model results are closer to the experimental data of the spontaneous fission fragments mass distributions than the WKB model. Also, experimental values are obtained

We study a stochastic population growth model with Allee effect, it is driven by correlated multiplicative and additive colored noises. The influences of noises on the statistical properties of the stochastic model are discussed. Applying an approximative Fokker-Planck equation, we first obtain the stationary probability distribution (SPD) of the stochastic model, and then present a more detailed discussion

This paper investigates the stochastic resonance phenomenon in two coupled harmonic oscillators with fluctuating mass. The fluctuation of the mass is modeled as a trichotomous noise. Applying the Shapiro-Loginov formula and the Laplace transform, the statistic synchronization between the two particles is obtained and defined. Then, the analytical expression of the output amplitude gain is derived.

Sensitivity with respect to physical change of any type of sensor depends upon structure of the sensor and sensing material. If sensor is sensitive with more than single physical change (pressure or temperature etc) than sensitivity will get affected because of conflict in impact due to multiple physical parameters. Depending upon the designer’s intuition and experience, a variety of shapes of sensor

The aim of this paper is to explore the complexity factor for those self-gravitating relativistic spheres whose evolution proceeds non- dynamically. We are adopting the definition of CF mentioned in (Herrera 2018 Phys. Rev. D 97 , 044010), modifying it to the static spherically symmetric case, within the framework of a modified gravity theory (the Palatini f ( R ) theory). In this respect, we have

The ‘Facility for Antiproton and Ion Research’ (FAIR) in Darmstadt will provide unique research opportunities for the investigation of fundamental open questions related to nuclear physics and astrophysics, including the exploration of QCD matter under extreme conditions, which governs the structure and dynamics of cosmic objects and phenomena like neutron stars, supernova explosions, and neutron star

We investigate quantum effects in the evolution of general systems. For studying such temporal quantum phenomena, it is paramount to have a rigorous concept and profound understanding of the classical dynamics in such a system in the first place. For this reason, we derive from first principles equations of motions that describe the classical propagation in quantum systems. A comparison of this classical

In order to obtain a better fit for the observational data, various cosmological models have been developed in the literature. For this purpose, we propose an adiabatic expansion of the Universe with a polytropic fluid matter-radiation content and a varying cosmological constant. Basic motivation of this study basically differs from the previous models because our model does not neglect the pressure

We consider the dynamics of the photon states in distant resonators coupled to a common bus resonator at different positions. The frequencies of distant resonators from a common bus resonator are equally detuned. These frequency detunings are kept larger than the coupling strengths of each resonator to the common bus resonator to satisfy the dispersive interaction regime. In the dispersive regime,

A method is proposed to induce strong aperiodic resonance in a linear frequency modulated signal excited nonlinear system. The phenomenon has application value in weak linear frequency modulated signal enhancement. The spectral amplification factor is used to measure the aperiodic resonance performance. By piece-wise analysis, appropriate system parameters are found. Then, a strong resonance output

We study in detail the onset of chaos and the probability measures formed by individual Bohmian trajectories in entangled states of two-qubit systems for various degrees of entanglement. The qubit systems consist of coherent states of 1-d harmonic oscillators with irrational frequencies. In weakly entangled states chaos is manifested through the sudden jumps of the Bohmian trajectories between successive

We argue that, under multidimensional position-dependent mass (PDM) settings, the Euler–Lagrange textbook invariance falls short and turned out to be vividly incomplete and/or insecure for a set of PDM-Lagrangians. We show that the transition from Euler–Lagrange component presentation to Newtonian vector presentation is necessary and vital to guarantee invariance. The totality of the Newtonian vector

It is shown that for the generally accepted values of the parameters of the spin-fermion model, taking into account the Coulomb interaction, both the one-site Hubbard U p and interaction between holes on the

Sounds of Science is the first movement of a symphony for many (scientific) instruments and voices, united in celebration of the frontiers of science and intended for a general audience. John Goodenough, the maestro who transformed energy usage and technology through the invention of the lithium-ion battery, opens the programme, reflecting on the ultimate limits of battery technology. This applied

The idea of a new model explaining the coherent nature of dark matter and dark energy is proposed. Recent works by Farnes (2018) and Socas-Navarro (2019) proposed a cosmological model and its critical analysis in which both dark matter and dark energy are replaced with a single fluid of negative mass. This paper presents a modification of this idea using the hypothesis about the existence of so-called

In this note we continue our analysis of the behaviour of self-adjoint Hamiltonians with a pair of identical point interactions symmetrically situated around the origin perturbing various types of ‘free Hamiltonians’ as the distance between the two centres shrinks to zero. In particular, by making the coupling constant to be renormalised dependent also on the separation distance between the centres

The extended x-ray absorption fine structure (EXAFS) spectroscopy is one of the powerful techniques for investigating local structures of crystalline as well as amorphous materials. It provides different structural information at various high temperatures due to anharmonicity. This work advances the anharmonic correlated Einstein model in EXAFS to investigate how pressure and temperature affect the

We consider a novel one dimensional model of a logarithmic potential which has super-super-exponential kink profiles as well as kink tails. We provide analytic kink solutions of the model—it has 3 kinks, 3 mirror kinks and the corresponding antikinks. While some of the kink tails are super-super-exponential, some others are super-exponential whereas the remaining ones are exponential. The linear stability

An exact solution of partial differential equations provides a lot of information for a model. Since obtaining such answers is generally very difficult or in some cases impossible, having powerful analytical methods in determining them seems very necessary. Unlike numerical methods, these methods have fewer constraints such as stability, convergence, and approximation error. This paper aims to consider

As one of the main optical wireless communication technologies, visible light communication (VLC) is considered a promising supplement in 5G/6G and the internet of things (IoT) networks. The multiple-input–multiple-output (MIMO) multiplexing scheme can significantly enhance a VLC system’s performance. To handle the blind MIMO demultiplexing, geometric vector extraction (GVE) algorithms are used in

The (2 + 1)-dimensional Schrödinger complex equations are essential physical models that describe the short-range pulse spread in nonlinear media fiber optics. We construct novel complex solutions to Schrödinger’s complex hyperbolic model by using two different techniques. One method is characterized by the efficient algebraic equations that eventually form. Meanwhile, it uses the dependency variable

This range of sizes coincides with that of the smallest bacteria as well as of the largest viruses, and is often considered to be the boundary between living and nonliving entities. Experiments are rapidly progressing towards

In a recent paper Boyle, Finn and Turok hypothesized that the Universe does not violate the CPT-symmetry. Thus, a pair of universes is obtained, one prior to the other following the big bang, while the request for CPT-invariance strictly constrains the vacuum states of quantized fields, with notable consequences on cosmological scenarios. Here we re-examine this proposal from the point of view of archaic

By virtue of the superoperator technique, we solve analytically the non-Markovian master equation that describes single-mode continuous variable system interacting with a structure reservoir. Our analytical solution allows us to investigate the non-Markovian effects on the dynamics of quantum coherence and non-classicality of Schrödinger cat states embedded in various types of structured reservoirs

A proposal is made to determine, by measurement, a possible anomaly in the electron’s orbital g-factor. It is generally assumed that the electron’s orbital g-factor is exactly 1, but it could be anomalous. Compared with the electron spin g-factor, the orbital g-factor has received very little experimental attention. A few possible experiments, in which an anomaly may be observed, are described.

For these confined systems, almost the same pressures are observed in the isotropic region, in comparison with the pressure of the corresponding bulk systems and theoretical results. In the nematic region

A technique for stabilizing the steady states in an array of either the star coupled or the all-to-all coupled FitzHugh–Nagumo (FHN) oscillators is described. To control the whole array a single oscillator or a small fraction of the oscillators can be involved.

We report the enhancement of spin–orbit torque (SOT) in Pt/Co/Pt and Pt/Co/AlOx multilayers by inserting rare-earth metal Tb layer. The inserted Tb layer thickness dependence of the critical switching current indicates that thicker Tb layer lead to more enhancement. The higher efficiency of SOT can be attributed to the increase of the effective spin Hall angle after inserting Tb layer, which has also

In particular, we investigate the interplay between the thermal baths properties and the size of the system. To this aim, we introduce a stochastic force field, which is simple enough to be energy-conserving for each particle of the chain

This paper applies the generalized exponential rational function method to a new extension of nonlinear Schrödinger equation. Many new analytical solutions are retrieved by choosing suitable coefficients of parameters under different family cases.

There was a misprint in the title of the paper: Quantum teleporation of thermofields (2019 Phys. Scr. 94 , 095 102). It should be read Quantum teleportation of thermofields. The word teleportation is correct all along the manuscript, but it is misprinted in the title even after the proofread of the paper, by the absence of a t . This lack of attention can be attributed exclusively to the main author
