Multi-Orbital Iterated Perturbation Theory Package

Purpose

This package contains code and sample data for generating Green's functions and self-energies of multi-orbital strongly correlated electron systems within dynamical mean field theory. The impurity solver is multi-orbital iterated perturbation theory.

Systems

The code has been tuned for cluster systems.

Contents

This package contains the source code and sample data.

Acknowledgments

The basic single-orbital IPT code was developed by N.S. Vidhyadhiraja (nsvraja@gmail.com). The multi-orbital extension and MPI wrapper for k-summation were done by Nagamalleswararao Dasari (nagamalleswararao.d@gmail.com). The optimization and benchmarks were carried out by Dasari, Peng (zpantz@gmail.com) and Wasim (wasimr.mondal@gmail.com) with the assistance of Mark Jarrell (jarrellphysics@gmail.com), Juana Moreno (moreno@phys.lsu.edu) and N.S. Vidhyadhiraja.
