✦ Synopsis

The solution of the SchrOdinger equation for a boson field interacting with a quantum particle is written as an expectation on a Poisson process counting the variations of the boson-oceupation numbers for each momentum. An energy cut-off is needed for the expectation to be meaningful.

The interaction of a spin with an electromagnetic field is treated utilizing the second-quantization method. The angular momentum operators are obtained from the particle creation and annihilation operators and the Jaynes-Cummings model is recovered from the present model Hamiltonian. A set of ficti
