Abstract:

The interaction Hamiltonian in the interaction representation for an arbitrary spin field coupled to the external gravitational field is obtained by using the method which is the extension of Yang-Feldman's one. The equal time commutator for the canonical energy density is derived directly from the integrability condition of the Schrödinger equation in the interaction representation. It is shown that the presence of ordinary interactions among fields does not alter drastically the form of commutator for free fields and also the relation between the present method and Schwinger's one based on the extended conservation law is discussed.
