Finite size scaling for a first order transition where a continuous symmetry is broken: The spin-flop transition in the 3D XXZ Heisenberg antiferromagnet
Jiahao Xu, Shan-Ho Tsai, D. P. Landau +1
Finite size scaling for a first order phase transition where a continuous symmetry is broken is developed using an approximation of Gaussian probability distributions with a phenom…
Exploring Replica-Exchange Wang-Landau sampling in higher-dimensional parameter space
Alexandra Valentim, Julio C. S. Rocha, Shan-Ho Tsai +4
We considered a higher-dimensional extension for the replica-exchange Wang-Landau algorithm to perform a random walk in the energy and magnetization space of the two-dimensional Is…
Improving Wang-Landau sampling with adaptive windows
A. G. Cunha-Netto, A. A. Caparica, Shan-Ho Tsai +2
Wang-Landau sampling (WLS) of large systems requires dividing the energy range into "windows" and joining the results of simulations in each window. The resulting density of states…
Phase transitions in ferro-antiferromagnetic bilayers with a stepped interface
D. P. Landau, Shan-Ho Tsai, Thomas C. Schulthess
We have studied magnetic ordering in ferro/antiferromagnetic (F/AF) bilayers using Monte Carlo simulations of classical Heisenberg spins. For both flat and stepped interfaces we ob…
Simulations of a classical spin system with competing superexchange and double-exchange interactions
Shan-Ho Tsai, D. P. Landau
Monte-Carlo simulations and ground-state calculations have been used to map out the phase diagram of a system of classical spins, on a simple cubic lattice, where nearest-neighbor…
Dynamic critical behavior of the classical anisotropic BCC Heisenberg antiferromagnet
Shan-Ho Tsai, Alex Bunker, D. P. Landau
Using a recently implemented integration method [Krech et. al.] based on an iterative second-order Suzuki-Trotter decomposition scheme, we have performed spin dynamics simulations…
