ffsim.NumNumAnsatzOpSpinBalanced¶

class ffsim.NumNumAnsatzOpSpinBalanced(norb, interaction_pairs, thetas)[source]¶

A number-number interaction ansatz operator.

The number-number interaction ansatz consists of a sequence of number-number interactions.

norb¶

The number of spatial orbitals.

interaction_pairs¶

The orbital pairs to apply the number-number interactions to.

thetas¶

The angles for the number-number interactions.

Methods

`from_diag_coulomb_mats`(diag_coulomb_mats)	Initialize the operator from a diagonal Coulomb matrix.
`from_parameters`(params, norb, interaction_pairs)	Initialize the operator from a real-valued parameter vector.
`n_params`(interaction_pairs)	Return the number of parameters of an ansatz with given settings.
`to_diag_coulomb_mats`()	Convert the operator to diagonal Coulomb matrices.
`to_parameters`()	Convert the operator to a real-valued parameter vector.
