openfermion.linalg.expectation_db_operator_with_pw_basis_state

Compute expectation value of a dual basis operator with a plane

wave computational basis state.

operator Dual-basis representation of FermionOperator to evaluate expectation value of. Can have at most 3-body terms. plane_wave_occ_orbitals (list): list of occupied plane-wave orbitals. n_spatial_orbitals (int): Number of spatial orbitals. grid (openfermion.utils.Grid): The grid used for discretization. spinless (bool): Whether the system is spinless.

A real float giving the expectation value.
