We study canonical-equilibrium properties of random field O(n) models involving classical continuous vector spins of n components with mean-field interactions and subject to disordered fields acting on individual spins. To this end, we empl...

A unified thermodynamic algorithm is presented for constructing thermodynamically consistent dynamical systems, i.e., systems that have Hamiltonian and dissipative parts that conserve energy while producing entropy. The algorithm is based o...
Nonspecular mechanism for chaotic ray scattering of internal waves in three-dimensional anisotropic stadiums [0.03%]

Fluids, subject to symmetry breaking by stratification, support propagation of anisotropic internal waves (IWs). In the vertical plane, rays representing energy paths obey a nonspecular reflection law, as their inclination is solely dictate...

We study a lattice model of a magnetic polymer where the XY spin variables are located on a self-avoiding walk on a regular lattice in two and three dimensions. We consider the regime where both spins and conformations are dynamic; thus, th...

This paper presents a versatile model for generating fractal complex networks that closely mirror the properties of real-world systems. By combining features of reverse renormalization and evolving network models, the proposed approach intr...

Using Monte Carlo simulations, we investigate the dynamical properties of the Baxter-Wu model under slow quenches, i.e., tuning the temperature slowly. For the cooling process, the scaling behavior of the excess defect density in the critic...

The accurate characterization of energy exchanges between nanoscale quantum systems and their environments is of paramount importance for quantum technologies, and central to quantum thermodynamics. Here, we show that, in order to accuratel...

Discovering constants of motion is meaningful in helping understand the dynamical systems, but it inevitably needs proficient mathematical skills and keen analytical capabilities. With the prevalence of deep learning, methods employing neur...

Nonthermal photoionized plasmas are now established in the laboratory and require models that treat the atomic processes and electron distribution self-consistently. We investigate the effects of inelastic thermalization in iron under inten...
Velocity distribution and diffusion of an athermal inertial run-and-tumble particle in a shear-thickening medium [0.03%]

We study the dynamics of an athermal inertial run-and-tumble particle moving in a shear-thickening medium in d=1. The viscosity of the medium is represented by a nonlinear function f(v)∼tan(v), while a symmetric dichotomous noise of streng...
