Finite-temperature properties of quasi-2D Bose-Einstein condensates
Kwangsik Nho, D. P. Landau
Using the finite-temperature path integral Monte Carlo method, we investigate dilute, trapped Bose gases in a quasi-two dimensional geometry. The quantum particles have short-range…
Bose-Einstein condensation of trapped atoms with dipole interactions
Kwangsik Nho, D. P. Landau
The path integral Monte Carlo method is used to simulate dilute trapped Bose gases and to investigate the equilibrium properties at finite temperatures. The quantum particles have…
Bose-Einstein Condensation Temperature of a Homogeneous Weakly Interacting Bose Gas : PIMC study
Kwangsik Nho, D. P. Landau
Using a finite-temperature Path Integral Monte Carlo simulation (PIMC) method and finite-size scaling, we have investigated the interaction-induced shift of the phase transition te…
Spin-dynamics simulations of the triangular antiferromagnetic XY model
Kwangsik Nho, D. P. Landau
Using Monte Carlo and spin-dynamics methods, we have investigated the dynamic behavior of the classical, antiferromagnetic XY model on a triangular lattice with linear sizes $L \le…
Scaling of thermal conductivity of helium confined in pores
Kwangsik Nho, Efstratios Manousakis
We have studied the thermal conductivity of confined superfluids on a bar-like geometry. We use the planar magnet lattice model on a lattice with . We…
Critical behavior of the planar magnet model in three dimensions
K. Nho, E. Manousakis
We use a hybrid Monte Carlo algorithm in which a single-cluster update is combined with the over-relaxation and Metropolis spin re-orientation algorithm. Periodic boundary conditio…
