| Abstract: | The system of a particle minimally coupled to a radiation field with an 1iltraviolet cut-off is considered. The Hamiltonian of the system is defined with non-perturbative approach; any assumptions on the magnitude of the absolute value of a coupling constant in the Hamiltonian is not required. It. is established that the ground state of the system, if exists, is unique and overlapps with the ground state of a decoupled Hamiltonian. |
