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
