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…
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…
Longitudinal magnetic excitations in classical spin systems
Alex Bunker, D. P. Landau
Using spin dynamics simulations we predict the splitting of the longitudinal spin wave peak in all antiferromagnets with single site anisotropy into two peaks separated by twice th…
Temperature dependent correlation length for the S=1/2 Quantum Heisenberg Antiferromagnet on the square lattice
Jae-Kwon Kim, D. P. Landau, Matthias Troyer
We present an analysis of high precision Monte Carlo data for the two dimensional S=1/2 quantum Heisenberg antiferromagnet up to obtained by the continuous time versio…
Numerical Computation of Finite Size Scaling Functions: An Alternative Approach to Finite Size Scaling
Jae-Kwon Kim, Adauto J. F. de Souza\cite{addr}, D. P. Landau
Using single cluster flip Monte Carlo simulations we accurately determine new finite size scaling functions which are expressed only in terms the variable , where $ξ_L…
