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…
Parallel Excluded Volume Tempering for Polymer Melts
Alex Bunker, Burkhard Duenweg
We have developed a technique to accelerate the acquisition of effectively uncorrelated configurations for off-lattice models of dense polymer melts which makes use of both paralle…
Spin dynamics simulations - a powerful method for the study of critical dynamics
D. P. Landau, Alex Bunker, Hans Gerd Evertz +2
Spin-dynamics techniques can now be used to study the deterministic time-dependent behavior of magnetic systems containing over 10^5 spins with quite good accuracy. This approach w…
Spin dynamics simulations of excitations and critical dynamics in RbMnF_3
D. P. Landau, Shan-Ho Tsai, Alex Bunker
Spin-dynamics simulations have been used to investigate the dynamic behavior of RbMnF_3, treating it as a classical Heisenberg antiferromagnet on a simple cubic lattice. Time-evolu…
Improved Spin Dynamics Simulations of Magnetic Excitations
D. P. Landau, Shan-Ho Tsai, M. Krech +1
Using Suzuki-Trotter decompositions of exponential operators we describe new algorithms for the numerical integration of the equations of motion for classical spin systems. These t…
Spin dynamics simulations of the magnetic dynamics of RbMnF and direct comparison with experiment
Shan-Ho Tsai, Alex Bunker, D. P. Landau
Spin-dynamics techniques have been used to perform large-scale simulations of the dynamic behavior of the classical Heisenberg antiferromagnet in simple cubic lattices with linear…
