Anderson's orthogonality catastrophe
Martin Gebert, Heinrich Küttler, Peter Müller
We give an upper bound on the modulus of the ground-state overlap of two non-interacting fermionic quantum systems with particles in a large but finite volume of -dime…

Anderson's Orthogonality Catastrophe for One-dimensional Systems
Heinrich Küttler, Peter Otte, Wolfgang Spitzer
We derive rigorously the leading asymptotics of the so-called Anderson integral in the thermodynamic limit for one-dimensional, non-relativistic, spin-less Fermi systems. The coeff…
