eigenstate

Model.eigenstate(quantum_nums)

Return the static-Hamiltonian eigenstate assigned to the local-\(S_z\) product-basis state.

Parameters:

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

Quantum numbers. It can be specified by three 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.

• By a bitstring such as "010", interpreted in the spin_names order using each spin’s qubit_subspace.

Return type:

ndarray | Array

Returns:

eigenstate (coefficient in the product basis)
