Majorana bound states in hybrid 2D Josephson junctions with ferromagnetic insulators
P. Virtanen, F. S. Bergeret, E. Strambini +2
We consider a Josephson junction consisting of superconductor/ferromagnetic insulator (S/FI) bilayers as electrodes which proximizes a nearby 2D electron gas. By starting from a ge…
On-Chip Cooling by Heating with Superconducting Tunnel Junctions
Giampiero Marchegiani, Pauli Virtanen, Francesco Giazotto
Heat management and refrigeration are key concepts for nanoscale devices operating at cryogenic temperatures. The design of an on-chip mesoscopic refrigerator that works thanks to…
Quasiparticle entropy in superconductor/normal metal/superconductor proximity junctions in the diffusive limit
Pauli Virtanen, Francesco Vischi, Elia Strambini +2
We discuss the quasiparticle entropy and heat capacity of a dirty superconductor-normal metal-superconductor junction. In the case of short junctions, the inverse proximity effect…
Colloquium: Nonequilibrium effects in superconductors with a spin-splitting field
F. Sebastian Bergeret, Mikhail Silaev, Pauli Virtanen +1
We review the recent progress in understanding the properties of spin-split superconductors under non-equilibrium conditions. Recent experiments and theories demonstrate a rich var…
Transport spectroscopy of induced superconductivity in the three-dimensional topological insulator HgTe
Jonas Wiedenmann, Eva Liebhaber, Johannes Kübert +6
The proximity-induced superconducting state in the 3-dimensional topological insulator HgTe has been studied using electronic transport of a normal metal-superconducting point cont…
High operating temperature in V-based superconducting quantum interference proximity transistors
Nadia Ligato, Giampiero Marchegiani, Pauli Virtanen +2
Here we report the fabrication and characterization of fully superconducting quantum interference proximity transistors (SQUIPTs) based on the implementation of vanadium (V) in the…
