Controllable critical Josephson current and 0-π transition in superconductor-insulator-superconductor heterostructures
Giorgos Livanas
We investigate Josephson junctions among conventional superconducting wires, in the presence of externally applied Zeeman fields and supercurrents. We demonstrate that the critical…
Nodal superconducting exchange coupling
Angelo Di Bernardo, Sachio Komori, Giorgio Livanas +4
The superconducting equivalent of giant magnetoresistance, involves placing a thin-film superconductor between two ferromagnetic layers. A change of magnetization-alignment in such…
Majorana Zero Modes in Ferromagnetic Wires without Spin-Orbit Coupling
Giorgos Livanas, Nikolaos Vanas, Georgios Varelogiannis
We present a novel controllable platform for engineering Majorana zero modes. The platform consists of a ferromagnetic metallic wire placed among conventional superconductors, whic…
Platform for controllable Majorana zero modes using superconductor/ferromagnet heterostructures
Giorgos Livanas, Nikos Vanas, Manfred Sigrist +1
We propose a novel platform for the creation and manipulation of Majorana zero modes consisting of a ferromagnetic metallic wire placed between conventional superconductors which a…
Inverse Proximity Effects at Spin-Triplet Superconductor-Ferromagnet Interface
O. Maistrenko, C. Autieri, G. Livanas +5
We investigate inverse proximity effects in a spin-triplet superconductor (TSC) interfaced with a ferromagnet (FM), assuming different types of magnetic profiles and chiral or heli…
Alternative paths to realize Majorana Fermions in Superconductor-Ferromagnet Heterostructures
G. Livanas, M. Sigrist, G. Varelogiannis
A fundamental obstacle for achieving quantum computation is local decoherence. One way to circumvent this problem rests on the concepts of topological quantum computation using non…
Nematicity from mixed S_{+-} + d_{x^2-y^2} states in iron-based superconductors
G. Livanas, A. Aperis, P. Kotetes +1
We demonstrate that in iron-based superconductors, the extended S_{+-} SC state coexists with the d_{x^2-y^2} state under generic conditions. The mixed S_{+-} + d_{x^2-y^2} SC is a…
