Compute expectation value of a 1-body dual-basis operator with a

plane wave computational basis state.

dual_basis_action Dual-basis action of FermionOperator to evaluate expectation value of. plane_wave_occ_orbitals (list): list of occupied plane-wave orbitals. grid (openfermion.utils.Grid): The grid used for discretization. spinless (bool): Whether the system is spinless.

A real float giving the expectation value.
