fqe.openfermion_utils.ascending_index_order

Permute a product of creation FermionOperators so that the index goes

fqe.openfermion_utils.ascending_index_order(
    ops: "FermionOperator",
    coeff: complex,
    order: str = ''
) -> "FermionOperator"

from the lowest to the highest inside of each spin sector and multiply by the correct parity.

Args
ops (FermionOperator) - A product of FermionOperators coeff (complex64) - The coefficient in front of the operator strings order (string) - specify if the operators should be returned in numerical order or not

coeff (complex64) - The coefficient in front of the operator strings

order (string) - specify if the operators should be returned in numerical order or not

Returns
(FermionOperator) - A product of FermionOperators with the correct sign
