The projection spectral theorem, quasi-free states and point processes

In this review paper, we demonstrate that several classes of point processes in a locally compact Polish space $X$ appear as the joint spectral measure of a rigorously defined particle density of a representation of the canonical anticommutation relations (CAR) or the canonical commutation relations (CCR) in a Fock space. For these representations of the CAR/CCR, the vacuum state on the corresponding $\ast$-algebra is quasi-free. The classes of point process that arise in such a way include determinantal and permanental point processes.
