DressedGraphene.gap_equation(k)

Calculate the gap equation.

The gap equation determines the order parameter for superconductivity by relating the pairings to the spectral properties of the BdG Hamiltonian.

Parameters:

knumpy.ndarray

List of k points in reciprocal space.

Returns:

numpy.ndarray

New pairing gap in orbital basis, adjusted to remove global phase.
