Enhanced binding revisited for a spinless particle in nonrelativistic QED

Enhanced binding revisited for a spinless particle in nonrelativistic QED

We consider a spinless particle coupled to a quantized Bose field and show that such a system has a ground state for two classes of short-range potentials which are alone too weak to have a zero-energy resonance.
