Comportamento multicrítico no modelo de Heisenberg frustrado: transições de fases clássica e quântica
Nunes, Wagner Antonio da Silva (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 01/09/2011)In this work we study the critical behavior of systems described by the Anysotropic- Heisenberg model of spin 1/2 with competitive interactions (J1-J2 Model) on planes, and interplane nearest-neighbor interactions. We ...
