A Szegő Limit Theorem Related to the Hilbert Matrix

Peter Otte

The Szegő limit theorem by Fedele and Gebert for matrices of the type identity minus Hankel matrix is proved for the special case where is the $N\times…

A cost effective and reliable environment monitoring system for HPC applications

Peter Bernd Otte, Dalibor Djukanovic

We present a slow control system to gather all relevant environment information necessary to effectively and reliably run an HPC (High Performance Computing) system at a high value…

Ground-state energy of one-dimensional free Fermi gases in the thermodynamic limit

Peter Otte, Wolfgang Spitzer

We study the ground-state energy of one-dimensional, non-interacting fermions subject to an external potential in the thermodynamic limit. To this end, we fix some (Fermi) energy $…

Anderson's orthogonality catastrophe in one dimension induced by a magnetic field

Hans Konrad Knörr, Peter Otte, Wolfgang Spitzer

According to Anderson's orthogonality catastrophe, the overlap of the -particle ground states of a free Fermi gas with and without an (electric) potential decays in the thermody…

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 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…

Convergence of Infinite Series in Bosonic Second Quantization

Peter Otte

The functor of second quantization as well as quadratic creation and annihilation operators on the bosonic Fock space are defined through possibly infinite series. The domain of co…

Boundedness properties of fermionic operators

Peter Otte

The fermionic second quantization operator is shown to be bounded by a power of the number operator given that the operator belongs to the -th von Neum…
