Spin Dynamics in the Two-Dimensional Spin 1/2 Heisenberg Antiferromagnet
A. F. Albuquerque, A. S. T. Pires, M. E. Gouvea
We present low-temperature dynamic properties of the quantum two-dimensional antiferromagnetic Heisenberg model with spin S=1/2. The calculation of the dynamic correlation function…

Spinwave damping in the two-dimensional ferromagnetic XY model
G. M. Wysin, M. E. Gouvea, A. S. T. Pires
The effect of damping of spinwaves in a two-dimensional classical ferromagnetic XY model is considered. The damping rate is calculated using the leading diagrams due to the…

Low Temperature Static and Dynamic Behavior of the Two-Dimensional Easy-Axis Heisenberg Model
M. E. Gouvea, G. M. Wysin, S. A. Leonel +3
We apply the self-consistent harmonic approximation (SCHA) to study static and dynamic properties of the two-dimensional classical Heisenberg model with easy-axis anisotropy. The s…
