openfermion.hamiltonians.jellium_model

Return jellium Hamiltonian as FermionOperator class.

    grid: openfermion.utils.Grid,
    spinless: bool = False,
    plane_wave: bool = True,
    include_constant: bool = False,

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).

FermionOperator The Hamiltonian of the model.
