gftool.lattice.sc.dos_moment(m, half_bandwidth)[source]¶

Calculate the m th moment of the simple cubic DOS.

The moments are defined as \(∫dϵ ϵ^m DOS(ϵ)\).

Parameters:	m : int The order of the moment. half_bandwidth : float Half-bandwidth of the DOS of the 3D simple cubic lattice.
Returns:	dos_moment : float The m th moment of the 3D simple cubic DOS.
Raises:	NotImplementedError Currently only implemented for a few specific moments m.
