Description

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. Versions of this program held in the CPC repository in Mendeley Data ADVK_v1_0; TPEM; 10.1016/j.cpc.2005.02.001 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
