Unveiling odd-frequency pairing around a magnetic impurity in a superconductor
Vivien Perrin, Flavio L. N. Santos, Gerbold C. Ménard +4
We study the unconventional superconducting correlations caused by a single isolated magnetic impurity in a conventional s-wave superconductor. Due to the local breaking of time-re…
Current-phase relations of InAs nanowire Josephson junctions: from interacting to multi-mode regimes
Sean Hart, Zheng Cui, Gerbold Menard +6
Gate-tunable semiconductor-superconductor nanowires with superconducting leads form exotic Josephson junctions that are a highly desirable platform for two types of qubits: those w…
Radio-frequency methods for Majorana-based quantum devices: fast charge sensing and phase diagram mapping
Davydas Razmadze, Deividas Sabonis, Filip K. Malinowski +9
Radio-frequency (RF) reflectometry is implemented in hybrid semiconductor-superconductor nanowire systems designed to probe Majorana zero modes. Two approaches are presented. In th…
Isolated pairs of Majorana zero modes in a disordered superconducting lead monolayer
Gerbold Ménard, Andrej Mesaros, Christophe Brun +4
Majorana zero modes are fractional quantum excitations appearing in pairs, each pair being a building block for quantum computation . Some possible signatures of these excitations…
Yu-Shiba-Rusinov bound states versus topological edge states in Pb/Si(111)
Gerbold C. Ménard, Christophe Brun, Raphaël Leriche +6
There is presently a tremendous activity around the field of topological superconductivity and Majorana fermions. Among the many questions raised, it has become increasingly import…
