- Graphene.diagonalize_bdg(k)#
Diagonalizes the BdG Hamiltonian.
This method computes the eigenvalues and eigenvectors of the Bogoliubov-de Gennes Hamiltonian, providing insight into the quasiparticle excitations in superconducting states.
- Parameters:
- k
numpy.ndarray List of k points in reciprocal space.
- k
- Returns:
- tuple
numpy.ndarray: Eigenvalues of the BdG Hamiltonian.numpy.ndarray: Eigenvectors corresponding to the eigenvalues of the BdG Hamiltonian.
