Class Documentation#

class rabiAndersonSC : public fermionBasis #

Anderson-like impurity model with a superconducting pairing term.

This model preserves spin as the only conserved quantum number while charge symmetry is broken by the superconducting pairing sector. It is used to study trion-like or superconducting impurity physics in a fermionic basis.

Public Functions
