Quantitative estimates on the enhanced binding for the Pauli-Fierz operator
(42K, AMS-Tex)

ABSTRACT.  For a quantum particle interacting with a short-range potential, 
we estimate from below the shift of its binding threshold, which 
is due to the particle interaction with a quantized radiation 
field.
