- DressedGraphene.calculate_density_of_states(k)#
Calculate the density of states (DOS).
This method computes the density of states by evaluating the eigenvalues of the BdG Hamiltonian over a specified energy range. The DOS provides insights into the allowed energy levels of the system.
- Parameters:
- k
numpy.ndarray List of k points in reciprocal space.
- k
- Returns:
- tuple
numpy.ndarray: Energy levels over which the density of states is calculated.
numpy.ndarray: The density of states corresponding to each energy level.
