LOWDIN: The any particle molecular orbital code

Abstract

LOWDIN is a computational program that implements the Any Particle Molecular Orbital (APMO) method. The current version of the code encompasses Hartree-Fock, second-order Møller-Plesset, configuration interaction, density functional, and generalized propagator theories. LOWDIN input file offers a unique flexibility, allowing users to exploit all the programs' capabilities to study systems containing any type and number of quantum species. This review provides a basic introduction to LOWDIN's key computational details and capabilities. © 2013 Wiley Periodicals, Inc. LOWDIN is a versatile computational program that implements the any particle molecular orbital (APMO) method. In the APMO framework, typical electronic structure methodologies are extended to any type of quantum particle. With the LOWDIN program, systems containing any type and number of quantum species can be studied. Copyright © 2013 Wiley Periodicals, Inc.
