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…

Superconducting diode effect in diffusive superconductors and Josephson junctions with Rashba spin-orbit coupling

Stefan Ilic, Pauli Virtanen, Daniel Crawford +2

We characterize the superconducting diode effect (SDE) in two-dimensional diffusive structures with Rashba spin-orbit coupling using the quasiclassical formalism. We consider both…

Superconducting Spintronic Heat Engine

Clodoaldo I. L. de Araujo, Pauli Virtanen, Maria Spies +7

Heat engines are key devices that convert thermal energy into usable energy. Strong thermoelectricity, at the basis of electrical heat engines, is present in superconducting spin t…

Signatures and characterization of dominating Kerr nonlinearity between two driven systems with application to a suspended magnetic beam

Andrii M Sokolov, Tero T. Heikkilä

We consider a model of two harmonically driven damped harmonic oscillators that are coupled linearly and with a cross-Kerr coupling. We show how to distinguish this combination of…

Dynamical Hall responses of disordered superconductors

Alberto Hijano, Sakineh Vosoughi-nia, F. Sebastián Bergeret +2

We extend the Mattis-Bardeen theory for the dynamical response of superconductors to include different types of Hall responses. This is possible thanks to a recent modification of…

Nonreciprocal Josephson linear response

Pauli Virtanen, Tero T. Heikkilä

We consider the finite-frequency response of multiterminal Josephson junctions and show how non-reciprocity in them can show up at linear response, in contrast to the static Joseph…
