Use the code

Once the executable exc created (it should be in \$prefix/bin after the make install) you can run the EXC code.

What you need is:

  • The ground state calculation output = kss file.
  • GW corrected energy = gw file.
  • Screening function = em1 file.
  • An input file (see below)

Then execute: exc -k file.kss -e file.em1 -g -i input > exc.log &

The commmand exc > exc.log & will look for a default in.kss and in.em1 files in the current directory. An input file will be also searched in the current directory.

Version 3.2 available

The new version of EXC is available. In particular the finite momentum transfer has been implemented.

New Release: v3.1

A new version of the code has been released: v3.1. Few changes and some bug corrections for this intermediate release.

New Release v3.0

A new version of the code has been released: v3.0.

Theoretical Spectroscopy Lectures

Electronic excitations are probed by experimental techniques such as optical absorption, EELS and photo-emission (direct or inverse).
