Linear bosonic quantum field theories arising from causal variational principles

Linear bosonic quantum field theories arising from causal variational principles

It is shown that the linearized fields of causal variational principles give rise to linear bosonic quantum field theories. The properties of these field theories are studied and compared with the axioms of local quantum physics. Distinguished quasi-free states are constructed.
