We consider three global chracteristic times for a one-dimensional Brownian motion x(τ) in the interval τ∈[0,t]: the occupation time t_{o} denoting the cumulative time where x(τ)>0, the time t_{m} at which the process achieves its globa...

The one-dimensional extended Hubbard model (EHM) in the atomic limit has recently been found to exhibit a curious thermal pseudo-transition behavior, which closely resembles first and second-order thermal phase transitions. This phenomenon,...

In the present work, the orientation of two-dimensional square crystals is studied using the radial distribution function (RDF) defined with the Chebyshev distance. Traditional RDF methods, based on the Euclidean metric, fail to detect chan...
Nonempirical approximation for the ionic thermal contribution to the equations of state based on average-atom models [0.03%]

A simple nonempirical approximation is proposed to calculate the ionic thermal contribution to the average-atom equations of state. The approximation represents the main regularities of temperature and mass-density dependences of the ionic ...

We study the propagation of both low- and high-amplitude ring-shaped sound waves in a two-dimensional square lattice of acoustic waveguides with Helmholtz resonators. We show that the inclusion of the Helmholtz resonators suppresses the inh...

In this paper, we performed the comprehensive studies of magnetic frustration properties in the Ising model on a decorated square lattice in the framework of an exact analytical approach based on the Kramers-Wannier transfer matrix method. ...

We investigate the effective temperature of a harmonic chain whose two ends are coupled to baths at different temperatures. We propose taking a weighted average temperature as the effective temperature of the system. The weighting factors a...

In this work, we investigate the swimming dynamics of a spheroidal squirmer near a flat wall for various aspect ratios using the direct-forcing fictitious domain method. Our results show that the swimming mode of a strong pusher undergoes t...
XY criticality arising from emergent symmetry in the three-dimensional Ashkin-Teller model [0.03%]

The Ashkin-Teller model plays a central role in studying the phase transitions of statistical mechanics models and condensed matter systems. Nevertheless, the phase transitions of the three-dimensional Ashkin-Teller model with competing int...
