Args |
grid (openfermion.utils.Grid): The discretization to use.
spinless (bool): Whether to use the spinless model or not.
plane_wave (bool): Whether to return in momentum space (True)
or position space (False).
include_constant (bool): Whether to include the Madelung constant.
Note constant is unsupported for non-uniform, non-cubic cells with
ions.
e_cutoff (float): Energy cutoff.
non_periodic (bool): If the system is non-periodic, default to False.
period_cutoff (float): Period cutoff, default to
grid.volume_scale() ** (1. / grid.dimensions).
