Yu-Shiba-Rusinov states in 2D superconductors with arbitrary Fermi contours
Jon Ortuzar, Stefano Trivini, Miguel Alvarado +5
Magnetic impurities on a superconductor induce sub-gap Yu-Shiba-Rusinov (YSR) bound states, localized at the impurity site and fading away from it for distances up to several nanom…
Superconducting spintronic tunnel diode
E. Strambini, M. Spies, N. Ligato +10
Diodes are key elements for electronics, optics, and detection. The search for a material combination providing the best performances for the required application is continuously o…
Spectral properties of Andreev crystals
Mikel Rouco, F Sebastian Bergeret, Ilya V Tokatly
We present an exhaustive study of Andreev crystals (ACs) -- quasi-one-dimensional superconducting wires with a periodic distribution of magnetic regions. The exchange field in thes…
Coexistence of superconductivity and spin-splitting fields in superconductor/ferromagnetic insulator bilayers of arbitrary thickness
Alberto Hijano, Stefan Ilić, Mikel Rouco +11
Ferromagnetic insulators can induce a strong exchange field in an adjacent superconductor via the magnetic proximity effect. This manifests as spin-splitting of the BCS density of…
Gap inversion in one-dimensional Andreev crystals
M. Rouco, F. S. Bergeret, I. V. Tokatly
We study a periodic arrangement of magnetic regions in a one-dimensional superconducting wire. Due to the local exchange field, each region supports Andreev bound states that hybri…
Charge transport through spin-polarized tunnel junction between two spin-split superconductors
Mikel Rouco, Subrata Chakraborty, Faluke Aikebaier +6
We investigate transport properties of junctions between two spin-split superconductors linked by a spin-polarized tunneling barrier. The spin-splitting fields in the superconducto…
Spectral Properties and Quantum Phase Transitions in Superconducting Junctions with a Ferromagnetic Link
Mikel Rouco, Ilya V. Tokatly, F. S. Bergeret
We study theoretically the spectral and transport properties of a superconducting wire with a magnetic defect. We start by modelling the system as a one dimensional magnetic Joseph…
Electron refrigeration in hybrid structures with spin-split superconductors
Mikel Rouco, Tero T. Heikkilä, F. Sebastian Bergeret
Electron tunneling between superconductors and normal metals has been used for an efficient refrigeration of electrons in the latter. Such cooling is a non-linear effect and usuall…
