Scaling of the Fano effect of the in-plane Fe-As phonon and the superconducting critical temperature in BaKFeAs
B. Xu, E. Cappelluti, L. Benfatto +11
By means of infrared spectroscopy we determine the temperature-doping phase diagram of the Fano effect for the in-plane Fe-As stretching mode in BaKFeAs.…
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…
Quantum confinement effects in Pb Nanocrystals grown on InAs
Tianzhen Zhang, Sergio Vlaic, Stéphane Pons +9
In the recent work of Ref.\cite{Vlaic2017-bs}, it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Cou…
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…
Unique interplay between superconducting and ferromagnetic orders in EuRbFeAs
V. S. Stolyarov, A. Casano, M. A. Belyanchikov +15
Transport, magnetic and optical investigations on EuRbFeAs single crystals evidence that the ferromagnetic ordering of the Eu magnetic moments at K, below t…
Spin-Orbit induced phase-shift in BiSe Josephson junctions
Alexandre Assouline, Cheryl Feuillet-Palma, Nicolas Bergeal +8
The transmission of Cooper pairs between two weakly coupled superconductors produces a superfluid current and a phase difference; the celebrated Josephson effect. Because of time-r…
