摘要
本文用平均场重整化群方法(MFRG)和离散路径积分表示(DPIR)的方法来研究自旋为2的无规横向伊辛模型在三峰分布纵场中(RFTIM)的相图和临界性质。
A approximate method combined by the mean-field renormalization group theory (MFRG) and the discretised path-integral representation (DPIR) is employed in the study of the spin-2 transverse Ising model in a trimodal random field (RFTIM). The phase diagrams and some critical properties are obtained and discussed.
