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…
Topological states of multiband superconductors with interband pairing
M. F. Holst, M. Sigrist, K. V. Samokhin
We study the effects of interband pairing in two-band s-wave and d-wave superconductors with D4h symmetry in both time-reversal invariant as well as time-reversal symmetry breaking…
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…
Effects of nucleation at a first-order transition between two superconducting phases: Application to CeRhAs
András L. Szabó, Mark H. Fischer, Manfred Sigrist
Recent experiments observed a phase transition within the superconducting regime of the heavy-fermion system CeRhAs when subjected to a -axis magnetic field. This phase…
Strain Modulation Effects on the Topological Properties of a Chiral p-Wave Superconductor
Yuto Shibata, Manfred Sigrist
We present a study of strain modulation effects on electronic structures of a two-dimensional single-band chiral p-wave superconductor within the BCS mean-field scheme. We employ a…
Superconductivity and Local Inversion-Symmetry Breaking
Mark H Fischer, Manfred Sigrist, Daniel F Agterberg +1
Inversion and time reversal are essential symmetries for the structure of Cooper pairs in superconductors. The loss of one or both leads to modifications to this structure and can…
