Lay Summary (German)

Lead
Im Festkörper übt die Spin-Bahn-Kopplung einen starken Einfluss auf dessen elektronische Eigenschaften aus, weil es den Spin der Elektronen mit der Bahnbewegung koppelt. Hieraus ergeben sich faszinierende Phänomene, wie z.B. eine neue quantenmechanische Phase, bekannt als topologischer Isolator. Auch in nicht topologischen Materialien können spin-polarisierte Zustände entstehen, die für die Spintronik von Bedeutung sind. Dies ermöglicht den Spin des Elektrons, statt seiner Ladung, auszunutzen.
Lay summary
Inhalt und Ziel des Forschungsprojekts

Das Hauptziel dieses Forschungsprojekts ist, mittels der spin- und winkelaufgelösten Photoemissions-Spektroskopie, die Rolle der Spin-Bahn-Kopplung in Festkörpern besser zu verstehen. Mit dieser Methode können elektronische Eigenschaften von neuartigen Materialien gezielt untersucht werden und anhand davon neue Materialien mit erwünschte Eigenschaften synthetisiert werden. Ein weiteres Ziel dieses Projekts ist exotische Zustände in korrelierten Systemen, wie zum Beispiel in Hochtemperatursupraleitern, zu untersuchen und helfen zu erklären.

Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojekts


Bei diesem Forschungsprojekt handelt es sich hauptsächlich um Grundlagenforschung auf einem sehr jungen Gebiet der Festkörperphysik. Die Resultate werden helfen ungelöste physikalische Probleme der heutigen Zeit zu verstehen, und um den Weg für eine neue Generation von technologischen Anwendungen vorzubereiten.

Abstract

The overall goal of this proposal is to study the role of spin-orbit interaction on the electronic structure of novel materials, with a specific focus on Rashba systems, topological insulators, and correlated systemsThe first aim of this project is to study the spin structure of various bulk and thin film topological insulators in contact with magnetic and superconducting materials by spin- and angle-resolved photoemission (SARPES). These measurements will be complemented by ab-initio calculations and STM and AFM measurements. Furthermore, different crystal faces of topological insulators and Rashba and topological systems involving unfilled d-states will be studied. The second goal is to study the influence of spin-orbit interaction in correlated systems through spin-dependent matrix element effects. Furthermore, different types of quasiparticle interactions are expected have a different spin structure of the self energy, which enters directly into the spectral function and can thus be detected through their typical fingerprint in the SARPES data.
