- TwoBand.bdg_hamiltonian(k)#
Generate the Bogoliubov-de Gennes (BdG) Hamiltonian.
The BdG Hamiltonian incorporates pairing interactions and is used to study superfluid and superconducting phases. This method constructs a 2x2 block Hamiltonian based on the normal state Hamiltonian and the pairing terms.
- Parameters:
- k
numpy.ndarray List of k points in reciprocal space.
- k
- Returns:
numpy.ndarrayThe BdG Hamiltonian matrix evaluated at the specified k points.
