Ce vendredi 25 mars à 11h nous aurons le plaisir d’accueillir Philipp Gohlke (https://www.math.uni-bielefeld.de/~pgohlke/) qui nous parlera des
Opérateurs de Schrödinger associés aux systèmes dynamiques
Voici son résumé :
Spectral properties of Schrödinger operators are relevant for the behavior of quantum mechanical systems in the presence of an external potential. In many interesting cases, the potential can be generated via a dynamical system.
There is a partial understanding and some general heuristics on how the spectrum of the Schrödinger operator depends on the type of dynamical systems.
We will discuss some of the known results and explore how they change if the potential is modified by a periodic background (joint work with D.Damanik and J.Fillman).
