How to perform some artificial modifications of the physics XG

This page gives hints on how to perform some artificial modifications of the physics with the ABINIT package.

Introduction

With a computer, one can consider non-physical modifications of the system to help the understanding the physics.

The nuclear masses and free electron mass can be modified. A fake space dependent chemical potenial can be added, see chempot, as well as the electrostatic potential of a slab, jellslab. A simple sine/cosine potential with a wavevector compatible with the (super)call can also be added, see qprtrb.
