Spin currents in crystals with spin-orbit coupling: multi-band effects in an effective Hamiltonian formalism
K. V. Samokhin, M. Sigrist, M. H. Fischer
When focusing on a few essential bands in an effective description of a material to calculate observable quantities, the respective operators have to be adjusted accordingly. Ignor…
Tunable quantum interferometer for correlated moiré electrons
Shuichi Iwakiri, Alexandra Mestre-Torà, Elías Portolés +8
Magic-angle twisted bilayer graphene (MATBG) can host an intriguing variety of gate-tunable correlated states, including superconducting and correlated insulator states. Junction-b…
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…
Solitonic in-gap modes in a superconductor-quantum antiferromagnet interface
J. L. Lado, M. Sigrist
Bound states at interfaces between superconductors and other materials are a powerful tool to characterize the nature of the involved systems, and to engineer elusive quantum excit…
