Abstract

An enhanced binding of an N-particle system linearly coupled to a scalar bose field is investigated, where N ≥ 2. It is not assumed that this system has a ground state for a zero coupling. It is shown, however, that there exists a ground state for sufficiently large values of a coupling constant. Basic ingredients of the proof are a weak coupling limit and a modified HVZ theorem.
