Soliton dynamics in 1D quantum antiferromagnets
A. Villares Ferrer, A. O. Caldeira, A. S. T. Pires
The problem of dissipative motion of solitons in the case of tetramethyl ammonium manganese chloride (TMMC) is studied as a function of the external magnetic field and the temperat…

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…
