netket.operator.boson.proj#
- netket.operator.boson.proj(hilbert, site, n, dtype=<class 'float'>)[source]#
Builds the projector operator \(|n\rangle\langle n |\) acting on the site-th of the Hilbert space hilbert and collapsing on the state with n bosons.
If hilbert is a non-Bosonic space of local dimension M, it is considered as a bosonic space of local dimension M.
- Parameters:
hilbert (
DiscreteHilbert
) – The hilbert space.site (
int
) – The site on which this operator acts.dtype (
Any
) – The datatype to use for the matrix elements.n (int)
- Return type:
- Returns:
An instance of {class}`nk.operator.LocalOperator`.
