Quantum effects and critical behavior in low-dimensional spin-1/2 systems
Authors:
- Grzegorz Kamieniarz
Abstract
The critical coupling and spontaneous magnetization curve for the 2D-Ising model are calculated using the effective-field method with correlations. An application of the method to the quantum 5 = 1/2 ID-Heisenberg model is presented and reliable low-temperature estimates of the specific heat are evaluated.
