The truncated polynomial expansion Monte Carlo method for fermion systems coupled to classical fields: a model independent implementation

Abstract
A software library is presented for the polynomial expansion method (PEM) of the density of states (DOS) introduced in [Y. Motome, N. Furukawa, J. Phys. Soc. Japan 68 (1999) 3853; N. Furukawa, Y. Motome, H. Nakata, Comput. Phys. Comm. 142 (2001) 410]. The library provides all necessary functions for the use of the PEM and its truncated version (TPEM) in a model independent way. The PEM/TPEM replaces the exact diagonalization of the one electron sector in models for fermions coupled to classic...

Title of program: TPEM
Catalogue Id: ADVK_v1_0

Nature of problem
The study of correlated electrons coupled to classical fields appears in the treatment of many materials of much current interest in condensed matter theory, e.g. manganites, diluted magnetic semi-conductors and high temperature superconductors among others.

本文提出了一种针对态密度（DOS）的多项式展开法（PEM）的软件库，该方法由Y. Motome、N. Furukawa在《日本物理社会》第68卷（1999年）第3853页及N. Furukawa、Y. Motome、H. Nakata在《计算机物理通讯》第142卷（2001年）第410页中提出。该库提供了使用PEM及其截断版本（TPEM）所需的所有必要函数，且使用方式与模型无关。PEM/TPEM可在模型独立的基础上替代费米子与经典场耦合模型中单电子部分的精确对角化。

程序名称：TPEM
目录编号：ADVK_v1_0

问题性质
在凝聚态理论中，研究关联电子与经典场耦合的现象，在处理许多当前备受关注的材料时都会出现，例如锰氧化物、稀释磁性半导体和高温超导体等。
