Interplay between Superconductivity and Altermagnetism in Disordered Materials and Heterostructures
Rodrigo de las Heras, Tim Kokkeler, Stefan Ilić +2
We study the interplay between superconductivity and altermagnetism in disordered systems using recently derived quantum kinetic transport equations. Starting from this framework,…
Fluxoid solitons in superconducting tapered tubes and bottlenecks
Tim Kokkeler, Mateo Uldemolins, Francisco Lobo +3
A thin-walled tubular superconductor develops a quantized fluxoid in the presence of an axial magnetic field. The fluxoid corresponds to the number of phase windings of the superco…
Superfluid weight in disordered flat-band superconductors as a competition between localization functionals
Kryštof Kolář, Tero T. Heikkilä, Päivi Törmä
According to Anderson's theorem, the gap of a time-reversal symmetric weak-coupling superconductor is unaffected by non-magnetic disorder. However, the superfluid weight (stiffness…
Josephson anomalous vortices
Dan Crawford, Stefan Ilić, 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…
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…
Superconducting junctions with flat bands
P. Virtanen, R. P. S. Penttilä, P. Törmä +3
We analyze the properties of flat-band superconductor junctions that behave differently from ordinary junctions containing only metals with Fermi surfaces. In particular, we show h…
