Existence of Schrodinger Evolution with Absorbing Boundary Condition
Lawrence Frolov, Stefan Teufel, Roderich Tumulka
Consider a non-relativistic quantum particle with wave function inside a region , and suppose that detectors are placed along the boundary . Th…
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 subspac…
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-t…
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-ca…
