Functionals for studies of BCS and unitary regimes
W-SLDA allows to investigate properties of fermionic systems in:
- Weakly interacting regime (BCS regime) by means of Bogoliubov-de Gennes equations (BdG).
- Strongly interacting regime, know as unitary Fermi gas (UFG), by means of Superfluid Local Density Approximation (SLDA).
