Lattice Boltzmann magnetohydrodynamics [PDF]
, 1994 Lattice gas and lattice Boltzmann methods are recently developed numerical schemes for simulating a variety of physical systems. In this paper a new lattice Boltzmann model for modeling two‐dimensional (2‐D) incompressible magnetohydrodynamics (MHD) is ...

Time-dependent currents of one-dimensional bosons in an optical lattice [PDF]
, 2009 We analyse the time dependence of currents in a one-dimensional (1D) Bose gas in an optical lattice. For a 1D system, the stability of currents induced by accelerating the lattice exhibits a broad crossover as a function of the magnitude of the ...

Computer Simulation of Particle Suspensions [PDF]
, 2006 Particle suspensions are ubiquitous in our daily life, but are not well understood due to their complexity. During the last twenty years, various simulation methods have been developed in order to model these systems.

Non-equilibrium steady states of ideal bosonic and fermionic quantum gases [PDF]
, 2015 We investigate non-equilibrium steady states of driven-dissipative ideal quantum gases of both bosons and fermions. We focus on systems of sharp particle number that are driven out of equilibrium either by the coupling to several heat baths of different ...

Density-dependent diffusion in the periodic Lorentz gas [PDF]
, 1999 We study the deterministic diffusion coefficient of the two-dimensional periodic Lorentz gas as a function of the density of scatterers. Results obtained from computer simulations are compared to the analytical approximation of Machta and Zwanzig [Phys ...

Liquid-gas-solid flows with lattice Boltzmann: Simulation of floating bodies
, 2012 This paper presents a model for the simulation of liquid-gas-solid flows by means of the lattice Boltzmann method. The approach is built upon previous works for the simulation of liquid-solid particle suspensions on the one hand, and on a liquid-gas free

Multiscale lattice Boltzmann approach to modeling gas flows [PDF]
, 2010 For multiscale gas flows, kinetic-continuum hybrid method is usually used to balance the computational accuracy and efficiency. However, the kinetic-continuum coupling is not straightforward since the coupled methods are based on different theoretical ...

Path integral Monte Carlo on a lattice: extended states. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2014 The equilibrium properties of a single quantum particle (qp) interacting with a classical gas for a wide range of temperatures that explore the system's behavior in the classical as well as in the quantum regime is investigated. Both the qp and atoms are

Simulation of Cavity Flow by the Lattice Boltzmann Method
, 1994 A detailed analysis is presented to demonstrate the capabilities of the lattice Boltzmann method. Thorough comparisons with other numerical solutions for the two-dimensional, driven cavity flow show that the lattice Boltzmann method gives accurate ...
