netket.operator.boson.number#
- netket.operator.boson.number(hilbert, site, dtype=<class 'float'>)[source]#
Builds the number operator \(\hat{a}^\dagger\hat{a}\) acting on the site-th of the Hilbert space hilbert.
If hilbert is a non-Bosonic space of local dimension M, it is considered as a bosonic space of local dimension M.
- Parameters:

- Returns:
The resulting Local Operator
