Nonequilibrium Relaxation and Critical Aging for Driven Ising Lattice Gases
(American Physical Society, 2012-03-13)
We employ Monte Carlo simulations to study the nonequilibrium relaxation of driven Ising lattice gases in two dimensions. Whereas the temporal scaling of the density autocorrelation function in the nonequilibrium steady ...
Spatial Variability Enhances Species Fitness in Stochastic Predator-Prey Interactions
(American Physical Society, 2008-12-19)
We study the influence of spatially varying reaction rates on a spatial stochastic two-species Lotka-Volterra lattice model for predator-prey interactions using two-dimensional Monte Carlo simulations. The effects of this ...
Dynein-Inspired Multilane Exclusion Process with Open Boundary Conditions
(MDPI, 2021-10-14)
Motivated by the sidewise motions of dynein motors shown in experiments, we use a variant of the exclusion process to model the multistep dynamics of dyneins on a cylinder with open ends. Due to the varied step sizes of ...
The role of the non-linearity in controlling the surface roughness in the one-dimensional Kardar-Parisi-Zhang growth process
(IOP Publishing, 2021-04-16)
We explore linear control of the one-dimensional non-linear Kardar-Parisi-Zhang (KPZ) equation with the goal to understand the effects the control process has on the dynamics and on the stationary state of the resulting ...
Relaxation and glassy dynamics in disordered type-II superconductors
(American Physical Society, 2011-11-18)
We study the nonequilibrium relaxation kinetics of interacting magnetic flux lines in disordered type II superconductors at low temperatures and low magnetic fields by means of a three-dimensional elastic-line model and ...
Requirements for the containment of COVID-19 disease outbreaks through periodic testing, isolation, and quarantine
(Virginia Tech, 2020-10-25)
We employ individual-based Monte Carlo computer simulations of a stochastic SEIR model variant on a two-dimensional Newman{Watts small-world network to investigate the control of epidemic outbreaks through periodic testing ...
Requirements for the containment of COVID-19 disease outbreaks through periodic testing, isolation, and quarantine
(IOP Publishing, 2022-01-21)
We employ individual-based Monte Carlo computer simulations of a stochastic SEIR model variant on a two-dimensional Newman–Watts small-world network to investigate the control of epidemic outbreaks through periodic testing ...
Stabilizing spiral structures and population diversity in the asymmetric May-Leonard model through immigration
(Springer, 2021-08-01)
We study the induction and stabilization of spiral structures for the cyclic three-species stochastic May-Leonard model with asymmetric predation rates on a spatially inhomogeneous two-dimensional toroidal lattice using ...
Effects of violating detailed balance on critical dynamics
(American Physical Society, 2002-01-28)
We present an overview of the effects of detailed-balance violating perturbations on the universal static and dynamic scaling behavior near a critical point. It is demonstrated that the standard critical dynamics universality ...
Reaction-controlled diffusion: Monte Carlo simulations
(American Physical Society, 2003-10)
We study the coupled two-species nonequilibrium reaction-controlled diffusion model introduced by Trimper [Phys. Rev. E 62, 6071 (2000)] by means of detailed Monte Carlo simulations in one and two dimensions. Particles of ...
