    grid: openfermion.utils.Grid,
    spinless: bool = False,
    e_cutoff: float = None,
    non_periodic: bool = False,

) -> openfermion.ops.FermionOperator

grid Grid

The discretization to use.

spinless bool

Whether to use the spinless model or not.

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).
