[CP2K-user] How the Fermi energy level is defined in CP2K?

[Matt W]

If you use diagonalisation and smearing it is the location of the chemical 
potential to get the correct number of electrons.

For OT / no smearing it is just given as the HOMO energy. At zero 
temperature it is not really defined in that case (anywhere between HOMO 
and LUMO would give same result).
