openfermion.linalg.jw_get_ground_state_at_particle_number
Compute ground energy and state at a specified particle number.
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

|
int
The particle number at which to compute the ground
energy and states
|
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
