Quantitative estimates on the enhanced binding for the Pauli-Fierz operator

TL;DR

This paper provides quantitative lower bounds on how a quantized radiation field enhances the binding energy of a quantum particle in a short-range potential.

Contribution

It introduces new estimates for the binding threshold shift caused by particle-radiation interactions in quantum systems.

Findings

Lower bounds on binding threshold shift established

Quantitative analysis of radiation field effects

Improved understanding of particle-field interactions

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.
