quant_met.bdg.diagonalize_bdg(hamiltonian, kgrid, delta_orbital_basis, q)

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:

q

kgrid

delta_orbital_basis

hamiltonian

Returns:

tuple

• numpy.ndarray: Eigenvalues of the BdG Hamiltonian.

• numpy.ndarray: Eigenvectors corresponding to the eigenvalues of the BdG Hamiltonian.
