fqe.fqe_decorators.build_hamiltonian

Build a Hamiltonian object for the fqe

fqe.fqe_decorators.build_hamiltonian(
    ops: Union[FermionOperator, fqe.hamiltonians.hamiltonian.Hamiltonian],
    norb: int = 0,
    conserve_number: bool = True,
    e_0: complex = (0.0 + 0.0j)
) -> "hamiltonian.Hamiltonian"

ops (FermionOperator, hamiltonian.Hamiltonian) - input operator as FermionOperator. If a Hamiltonian is passed as an argument, this function returns as is.

norb (int) - the number of orbitals in the system

conserve_number (bool) - whether the operator conserves the number

e_0 (complex) - the scalar part of the operator

(hamiltonian.Hamiltonian) - General Hamiltonian that is created from ops
