Interaction Hamiltonians of some models beyond the rotating wave approximation are just a product of two commuting operators. The evolution operator of such models can be transformed into product of two independent chronological exponents with the help of Hubbard-Stratonovich transformation. We use such a representation of the evolution operator to exactly describe a two-level atom in a photonic thermostat.
