Szegő-type determinant asymptotics for generalized Hilbert matrices with edge eigenvalues
Martin Gebert, Heinrich Küttler
We compute the large- asymptotics of the determinant of the identity plus or minus a generalized Hilbert matrix. For and $δ\in \mathbb{R} \setminus \{-1, -2,…
The exponent in the orthogonality catastrophe for Fermi gases
Martin Gebert, Heinrich Küttler, Peter Müller +1
We quantify the asymptotic vanishing of the ground-state overlap of two non-interacting Fermi gases in -dimensional Euclidean space in the thermodynamic limit. Given two one-par…
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…
