eigenstate

Model.eigenstate(quantum_nums)

Return the eigenstate of the static Hamiltonian that has the largest overlap with the product basis state described by quantum_nums.

Parameters:

quantum_nums (Dict[str, float] | Tuple[float, ...]) –

Quantum numbers. It can be specified by two different ways:

  • By a dict whose keys correspond to the spin names and values correspond to the quantum numbers.

  • By a tuple containing the quantum numbers in the same order as indicated by the spin_names.

Return type:

ndarray

Returns:

eigenstate (coefficient in the product basis)
