概要
- 論文の詳細を見る
A Bose lattice gas of particles with spin 1/2, equivalent to the Heisenberg model, is presented. An approximate method of the cluster variation method, to be called as QCVM, is applied to this system, by which we can discuss the phase transition as well as spin waves at low temperatures. The study here is restricted to the ferromagnetic Heisenberg model on the s . c. lattice.
