Superconductivity and other phase transitions in a hybrid Bose-Fermi mixture formed by a polariton condensate and an electron system in two dimensions
Ovidiu Cotleţ, Sina Zeytinoǧlu, Manfred Sigrist +2
Interacting Bose-Fermi systems play a central role in condensed matter physics. Here, we analyze a novel Bose-Fermi mixture formed by a cavity exciton-polariton condensate interact…
Topological Crystalline Superconductivity in Locally Non-centrosymmetric Multilayer Superconductors
Tomohiro Yoshida, Manfred Sigrist, Youichi Yanase
Topological crystalline superconductivity in the locally non-centrosymmetric multilayer superconductors (SCs) is proposed. We study the odd-parity pair-density wave (PDW) state ind…
Minimal Model of Spin-Transfer Torque and Spin Pumping caused by Spin Hall Effect
Wei Chen, Manfred Sigrist, Jairo Sinova +1
In the normal metal/ferromagnetic insulator bilayer (such as Pt/YFeO) and the normal metal/ferromagnetic metal/oxide trilayer (such as Pt/Co/AlO) where spi…
Surface-state spin textures and mirror Chern numbers in topological Kondo insulators
Markus Legner, Andreas Rüegg, Manfred Sigrist
The recent discovery of topological Kondo insulators has triggered renewed interest in the well-known Kondo insulator samarium hexaboride, which is hypothesized to belong to this f…
Evidence for time-reversal symmetry breaking of the superconducting state near twin-boundary interfaces in FeSe
T. Watashige, Y. Tsutsumi, T. Hanaguri +9
Junctions and interfaces consisting of unconventional superconductors provide an excellent experimental playground to study exotic phenomena related to the phase of the order param…
Resonant scattering induced thermopower in one-dimensional disordered systems
D. Müller, W. J. Smit, M. Sigrist
This study analyzes thermoelectric properties of a one-dimensional random conductor which shows localization effects and simultaneously includes resonant scatterers yielding sharp…
