Quantum Geometric Helical Superconductivity
Aaron Dunbrack, Pauli Virtanen, Tero T. Heikkilä
Several physical phenomena in superconductors, such as helical superconductivity and the diode effect, rely on breaking time-reversal symmetry. This symmetry-breaking is usually ac…

Detection of spin- and valley-polarized states in van der Waals materials via thermoelectric and non-reciprocal transport
Oladunjoye A. Awoga, Pauli Virtanen, Tero T. Heikkilä +1
We predict thermoelectric and current rectification effects in hybrid junctions formed by Ising superconductors and materials hosting valley-polarized states. Both effects originat…

Josephson anomalous vortices
Dan Crawford, Stefan IliÄ, Pauli Virtanen +1
We show that vortices with circulating current, related with odd-frequency triplet pairing, appear in Josephson junctions where the barrier is a weak ferromagnet with strong spin-o…
