netket.operator.spin.identity

netket.operator.spin.identity(hilbert, dtype=None, *, cls=<class 'netket.operator._local_operator.jax.LocalOperatorJax'>)

Builds the \(\mathbb{I}\) identity operator.

Parameters:

• hilbert (DiscreteHilbert) – The hilbert space.

• dtype (Union[None, str, type[Any], dtype, _SupportsDType]) – The datatype to use for the matrix elements.

• cls (type[_LocalOperatorT])

Return type:

TypeVar(_LocalOperatorT, bound= LocalOperatorBase)

Returns:

An instance of {class}`nk.operator.LocalOperator`.
