Majorana Kramers pairs in Rashba double nanowires with interactions and disorder
Manisha Thakurathi, Pascal Simon, Ipsita Mandal +2
We analyze the effects of electron-electron interactions and disorder on a Rashba double-nanowire setup coupled to an s-wave superconductor, which has been recently proposed as a v…
Topological Phase Detection in Rashba Nanowires with a Quantum Dot
Denis Chevallier, Paweł Szumniak, Silas Hoffman +2
We study theoretically the detection of the topological phase transition occurring in Rashba nanowires with proximity-induced superconductivity using a quantum dot. The bulk states…
DIII Topological Superconductivity with Emergent Time-Reversal Symmetry
Christopher Reeg, Constantin Schrade, Jelena Klinovaja +1
We find a new class of topological superconductors which possess an emergent time-reversal symmetry that is present only after projecting to an effective low-dimensional model. We…
Finite-size effects in a nanowire strongly coupled to a thin superconducting shell
Christopher Reeg, Daniel Loss, Jelena Klinovaja
We study the proximity effect in a one-dimensional nanowire strongly coupled to a finite superconductor with a characteristic size which is much shorter than its coherence length.…
Magnonic topological insulators in antiferromagnets
Kouki Nakata, Se Kwon Kim, Jelena Klinovaja +1
Extending the notion of symmetry protected topological phases to insulating antiferromagnets (AFs) described in terms of opposite magnetic dipole moments associated with the magnet…
Three-Dimensional Fractional Topological Insulators in Coupled Rashba Layers
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We propose a model of three-dimensional topological insulators consisting of weakly coupled electron- and hole-gas layers with Rashba spin-orbit interaction stacked along a given a…
