openfermion.linalg.valdemoro_reconstruction

Build a 3-RDM by cumulant expansion and setting 3rd cumulant to zero

Main aliases

openfermion.linalg.valdemoro_reconstruction(
    tpdm, n_electrons
)

d3 approx = D ^ D ^ D + 3 (2C) ^ D

tpdm has normalization (n choose 2) where n is the number of electrons

Args
tpdm (np.ndarray): four-tensor representing the two-RDM n_electrons (int): number of electrons in the system

Returns
six-tensor reprsenting the three-RDM
