# 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.
