The iDEA code The iDEA Code

The iDEA code (interacting Dynamic Electrons Approach) is a Python software suite (with Cython extensions) developed in Rex Godby's group at the University of York since 2010. It has a central role in a number of research projects related to many-particle quantum mechanics for electrons in matter.

iDEA's main features are:

*Density-functional theory, and time-dependent density-functional theory
