Abstract: Relativistic quantum theories are usually thought of as being quantum field theories, but this is not the only possibility. Here, we consider relativistic quantum theories with a fixed number of particles that interact neither through… read more here.

Abstract: We prove that the quantum decomposition of a classical random variable, or random field, is a very general phenomenon involving only an increasing filtration of Hilbert spaces and a family of Hermitean operators increasing by… read more here.
