Lay summary

Die theoretische Festkörperphysik befasst sich mehrheitlich mit der quantenmechanischen Beschreibung elektronischer Phänomene in der kondensierten Materie. Dies umfasst das Modellieren von Phänomenen wie der elektrischen Leitfähigkeit, Magnetismus oder Supraleitung. In den letzten Jahren hat das Konzept des "topologischen Isolators" viel Aufmerksamkeit erhalten. Ein topologischer Isolator ist ein ganz spezielles Material: Das innere eines topologischen Isolators ist, wie es der Name vermuten lässt, sein elektrischer Isolator bei dem keine Ströme fliessen können. Die Oberfläche ist aber garantiert ein Leiter. Und nicht nur ein gewöhnlicher elektrischer Leiter sondern ein perfekter Leiter mit weiteren interessanten, technologisch relevanten Eigenschaften.

Wir versuchen nun diese Ideen auf das Design von mechanischen Metamaterialien zu übersetzten. Mechanische Metamaterialien verdanken ihre mechanischen Eigenschaften nicht ihrer mikroskopischen Komposition, sondern einer cleveren Strukturierung ihres Aufbaus. Bei dieser Strukturierung kann man nun versuchen die Phänomenologie der topologischen Isolatoren zu verwenden um Funktionen wie perfekte akustische Wellenleiter, Wärmedioden oder Vibrationsisolatoren zu erhalten.

Abstract

In this proposal I outline two different branches of my research. First, I am interested in the application of topological band theory to the engineering of acoustic metamaterials. We performed experiments in this field and I plan to strengthen this activity and will supplement the experimental efforts with theoretical works deepening the link between electronic topological insulators and mechanical systems. Second, the proposal contains several projects in the field of non-eqiulibrium quantum dynamics. In particular on the investigation of many-body localization in the presence of a bath and on polariton induced superconductivity.
