openfermion.linalg.jw_get_ground_state_at_particle_number

Compute ground energy and state at a specified particle number.

Main aliases

openfermion.linalg.jw_get_ground_state_at_particle_number(
    sparse_operator, particle_number
)

Assumes the Jordan-Wigner transform. The input operator should be Hermitian and particle-number-conserving.

Args
`sparse_operator`	`sparse` A Jordan-Wigner encoded sparse matrix.
`particle_number`	`int` The particle number at which to compute the ground energy and states

Args

Returns
`ground_energy`	`float` The lowest eigenvalue of sparse_operator within the eigenspace of the number operator corresponding to particle_number.
`ground_state`	`ndarray` The ground state at the particle number

ground_energy

float

The lowest eigenvalue of sparse_operator within the eigenspace of the number operator corresponding to particle_number.

ground_state

ndarray

The ground state at the particle number
