D=2和3维自旋S=1和3/2的Blume-Capel模型

The Blume-Capel model for spins S=1 and 3/2 in dimensions d=2 and 3

P. Butera, M. Pernici

摘要:

本文对具有不同自旋值和存在磁场的二维和三维二分晶格(sq,sc和bcc)上的Blume-Capel模型的主要观测量,导出了在高温下的24阶展开式和在低温下的11阶展开式.所有的膨胀系数都精确地计算为晶体和磁场的函数。在自旋S=1和S=3/2的两种研究最多的情况下,分析了模型的几个关键性质。

英文摘要:

Expansions through the 24th order at high-temperature and up to 11th order at low-temperature are derived for the main observables of the Blume-Capel model on bipartite lattices (sq, sc and bcc) in 2d and 3d with various values of the spin and in presence of a magnetic field. All expansion coefficients are computed exactly as functions of the crystal and magnetic fields. Several critical properties of the model are analyzed in the two most studied cases of spin S=1 and S=3/2.
