Canonical Typicality For Other Ensembles Than Micro-Canonical
Stefan Teufel, Roderich Tumulka, Cornelia Vogel
We generalize Lévy's lemma, a concentration-of-measure result for the uniform probability distribution on high-dimensional spheres, to a much more general class of measures, so-cal…
Typical Macroscopic Long-Time Behavior for Random Hamiltonians
Stefan Teufel, Roderich Tumulka, Cornelia Vogel
We consider a closed macroscopic quantum system in a pure state evolving unitarily and take for granted that different macro states correspond to mutually orthogonal subspace…
Time Evolution of Typical Pure States from a Macroscopic Hilbert Subspace
Stefan Teufel, Roderich Tumulka, Cornelia Vogel
We consider a macroscopic quantum system with unitarily evolving pure state and take it for granted that different macro states correspond to mutually orthogon…
Finding spectral gaps in quasicrystals
Paul Hege, Massimo Moscolari, Stefan Teufel
We present an algorithm for reliably and systematically proving the existence of spectral gaps in Hamiltonians with quasicrystalline order, based on numerical calculations on finit…
From orbital magnetism to bulk-edge correspondence
Horia D. Cornean, Massimo Moscolari, Stefan Teufel
By extending the gauge covariant magnetic perturbation theory to operators defined on half-planes, we prove that for random ergodic magnetic Schrödinger operators, the zero-te…
Local stability of ground states in locally gapped and weakly interacting quantum spin systems
Joscha Henheik, Stefan Teufel, Tom Wessel
Based on a result by Yarotsky (J. Stat. Phys. 118, 2005), we prove that localized but otherwise arbitrary perturbations of weakly interacting quantum spin systems with uniformly ga…
