Quantitative estimates on the enhanced binding for the Pauli-Fierz operator
Jean-Marie Barbaroux, Helmut Linde, Semjon Vugalter
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 quantize…

Walter H. Aschbacher, Jean-Marie Barbaroux
We study the transversal XY spin-spin correlations in the non-equilibrium steady state constructed in \cite{AP03} and prove their spatial exponential decay close to equilibrium.
