Development of a collision table for three dimensional lattice gases
A lattice gas is a species of cellular automaton used for numerically simulating fluid flows. TransGas [9], the lattice gas code currently in use at the CSIR, is based on the FHP-I model [5], and is used to perform various two-dimensional flow simulations. In order to broaden the scope of the …

Monte Carlo analysis of non-equilibrium steady states and relaxation kinetics in driven lattice gases
… auto-correlation function in driven lattice gases, with particle exclusion and periodic boundary conditions in one, two, and three dimensions using precise Monte Carlo simulations of larger system sizes than previous studies. In the one-dimensional asymmetric exclusion process on a …

Steady State Properties of Some Driven Diffusive Systems
… variations of the prototype, the driven Ising lattice gas. Our first system studied is the bilayer model, a stack of two driven Ising lattice gases allowed to interact. We study this model using a very simple analytic approximation, the high temperature expansion. Building on existing …

Dynamics of ultracold bosons in a disordered optical lattice
… use 87Rb atoms trapped in a disordered optical lattice to realize the 3D Bose Hubbard model, with independently, dynamically tunable lattice depth and disorder strength. The equilibrium behavior of the Bose Hubbard and disordered Bose Hubbard models are understood, but there are many outstanding …

Controlling non-equilibrium dynamics in lattice gas models
… variant of the Katz–Lebowitz–Spohn (KLS) driven lattice gas in two dimensions, where the lattice is split into two regions that are coupled to heat baths with distinct temperatures T > T<sub>c</sub> and T<sub>c</sub> respectively, where T<sub>c</sub> indicates the critical temperature for phase …

Hydrodynamic behaviour of active and multi-species exclusion processes
… develop an exact hydrodynamic description for a lattice model of active matter with exclusion. The macroscopic limit is an integro-differential equation for the particles' density in phase space (positions and orientations) and includes nonlinearities in both the diffusive and advective …
