netket.operator.spin.sigmap#
- netket.operator.spin.sigmap(hilbert, site, dtype=<class 'float'>)[source]#
Builds the \(\sigma^{+} = \frac{1}{2}(\sigma^x + i \sigma^y)\) operator acting on the site-th of the Hilbert space hilbert.
If hilbert is a non-Spin space of local dimension M, it is considered as a (M-1)/2 - spin space.
- Parameters:
hilbert (
AbstractHilbert
) – The hilbert spacesite (
int
) – the site on which this operator actsdtype (Any) –
- Return type:
- Returns:
a nk.operator.LocalOperator
