openfermion.linalg.get_gap

Compute gap between lowest eigenvalue and first excited state.

Main aliases

openfermion.linalg.get_gap(
    sparse_operator, initial_guess=None
)

Args
sparse_operator (LinearOperator): Operator to find the ground state of. initial_guess (ndarray): Initial guess for eigenspace. A good guess dramatically reduces the cost required to converge.

Returns: A real float giving eigenvalue gap.
