What is edrixs?

EDRIXS is an open source toolkit for simulating XAS and RIXS spectra based on exact diagonalization of model Hamiltonians. It was started as part of COMSCOPE project in the Center for Computational Material Spectroscopy and Design, Brookhaven National Laboratory and is now maintained and developed in collaboration between the Condensed Matter Physics and Materials Science Division and the National Syncrotron Light Source II.
