We consider the mean-field classical Heisenberg model and obtain detailed information about the magnetization by studying the model on a complete graph and sending the number of vertices to infinity. ...
The field induced quantum critical properties of the three dimensional spin-1/2 anisotropic antifer-romagnetic Heisenberg model has been studied. We have investigated the quantum phase transition betw...
In the present paper, we study spin- 1 2 antiferromagnetic (AF) Heisenberg model on layered anisotropic triangular lattice and obtain its phase structure. We use the Schwinger bosons for representing ...
