## Interfacial adsorption in Potts models on the square lattice

The European Physical Journal B. 2015. Vol. 88. P. 204.

We study the effect of interfacial phenomena in two-dimensional perfect and random (or disordered)

q-state Potts models with continuous phase transitions, using, mainly, Monte Carlo techniques.

In particular, for the total interfacial adsorption, the critical behavior, including corrections to scaling,

are analyzed. The role of randomness is scrutinized. Results are discussed applying scaling arguments and

invoking findings for bulk critical properties. In all studied cases, i.e., q = 3, 4, and q = 8, the spread of

the interfacial adsorption profiles is observed to increase linearly with the lattice size at the bulk transition

point.

We report on numerical investigation of fractal properties of critical interfaces in two-dimensional Potts models. Algorithms for finding percolating interfaces of Fortuin-Kasteleyn clusters, their external perimeters and interfaces of spin clusters are presented. Fractal dimensions are measured and compared to exact theoretical predictions. ...

We examine the question of the influence of sparse long-range communications on the synchronization in parallel discrete event simulations (PDES). We build a model of the evolution of local virtual times (LVT) in a conservative algorithm including several choices of local links. All network realizations belong to the small-world network class. We find that synchronization ...

A Monte Carlo simulation study of the critical and off-critical behavior of the Baxter–Wu model, which belongs to the universality class of the 4-state Potts model, was performed. We estimate the critical temperature window using known analytical results for the specific heat and magnetization. This helps us to extract reliable values of universal combinations of ...

The critical behavior of the four-component Potts model on a hexagonal lattice is studied numerically. The modified Wang-Landau method with the control of the density of states estimation accuracy is used. A finite-dimensional analysis of the results obtained confirms the presence of a second-order phase transition with critical exponents corresponding to the universality class of ...

Abstract
We present a solution of the nonlinear renormalization group equations leading
to the dominant and subdominant singular behaviors of physical quantities (free
energy density, correlation length, internal energy, specific heat, magnetization,
susceptibility and magneto caloric coefficient) at the critical temperature in a
non-vanishing magnetic field. The solutions (i) lead to exact cancellation of
logarithmic corrections in universal amplitude ratios ...

The problem of planar oscillations of a pendulum with variable length suspended on the Moon’s surface is considered. It is assumed that the Earth and Moon (or, in the general case, a planet and its satellite, or an asteroid and a spacecraft) revolve around the common center of mass in unperturbed elliptical Keplerian orbits. We ...

Warm dense hydrogen is studied in the region of fluid–fluid phase transition within
the framework of the density functional theory. We report a procedure of obtaining
metastable states and calculate the equation of state. Metastable states are diagnosed by pair correlation functions and values of conductivity. We obtain a strong

We simulate the oscillation of the viscous drop in the viscous liquid. We combine methods of chromodynamics model and Shan-Chen pseudo-potential for the immiscible fluids. We measure the frequency of the first nontrivial eigenmode using the initial ellipsoid form of the drop. Drop oscillates about the equilibrium spherical form of radius $R$. Computed frequency as ...

We investigate the time evolution of the momentum of an impurity atom injected into a degenerate Tonks-Girardeau gas. We establish that given an initial momentum p0 the impurity relaxes to a steady state with a nonvanishing momentum p∞. The nature of the steady state is found to depend drastically on whether the masses of the impurity and the host ...

We consider a spatially distributed evolutionary game based on the Prisoner’s
Dilemma with agents arranged on a three-dimensional simple cubic lattice. Comparing to twodimensional arrangements, we find that the larger number of neighbors favors the formation of
spatial chaos: the steady state of the game is chaotic unless the payoff parameter is small. ...

The exciton valley dynamics in van der Waals heterostructures with transition metal dichalcogenide monolayers is driven by the long-range exchange interaction between the electron and the hole in the exciton. It couples the states active in the opposite circular polarizations resulting in the longitudinal-transverse splitting of excitons propagating in the monolayer plane. Here we study ...

The proof of the security of quantum key distribution is a rather complex problem. Security is
defined in terms different from the requirements imposed on keys in classical cryptography. In quantum
cryptography, the security of keys is expressed in terms of the closeness of the quantum state of an eavesdropper
after key distribution to an ideal quantum state ...

It is often suggested that inter-particle distance in stable dusty plasma structures decreases with cooling as a square root of neutral gas temperature. Deviations from this dependence (up to the increase at cryogenic temperatures) found in the experimental results for the pressures range 0.1–8.0 mbar and for the currents range 0.1–1.0 mA are given. Inter-particle ...
