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…
