magnopy.LSWT.omega#

method

LSWT.omega(k, relative=False)[source]#
Parameters:
k(3,) array-like

Reciprocal vector

relativebool, default False

If relative=True, then k is interpreted as given relative to the reciprocal unit cell. Otherwise it is interpreted as given in absolute coordinates.

Returns:
omegas(M, ) numpy.ndarray

Array of omegas. Note, that data type is complex. If the ground state is correct, then the complex part should be zero.
