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

Calculate the m th moment of the body-centered 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 body-centered cubic lattice.

Returns:
dos_moment : float

The m th moment of the 3D body-centered cubic DOS.

Raises:
NotImplementedError

Currently only implemented for a few specific moments m.
