Calculate the spectral gap.
This method evaluates the spectral gap of the system by examining the density of states. It identifies the range of energy where there are no states and thus determines the energy difference between the highest occupied and lowest unoccupied states.
- Parameters:
- k
numpy.ndarray List of k points in reciprocal space.
- k
- Returns:
- float
The calculated spectral gap.
