Non-unitary multiorbital superconductivity from competing interactions in Dirac materials
Tobias M. R. Wolf, Maximilian F. Holst, Manfred Sigrist +1
Unconventional superconductors represent one of the most intriguing quantum states of matter. In particular, multiorbital systems have the potential to host exotic non-unitary supe…
Magnetoelectric torque and edge currents caused by spin-orbit coupling
Wei Chen, Manfred Sigrist
Using a tight-biding model, we elaborate that the previously discovered out-of-plane polarized helical edge spin current caused by Rashba spin-orbit coupling can be attributed to t…
Magnetoelectric torque and edge currents in spin-orbit coupled graphene nanoribbons
Matheus S. M. de Sousa, Manfred Sigrist, Wei Chen
For graphene nanoribbons with Rashba spin-orbit coupling, the peculiar magnetic response due to the presence of a magnetization and geometric confinement are analyzed within a tigh…
