On the importance of measuring accurately LDOS maps using scanning tunneling spectroscopy in materials presenting atom-dependent charge order: the case of the correlated Pb/Si(111) single atomic layer
C. Tresca, T. Bilgeri, G. Menard +11
We show how to properly extract the local charge order in two-dimensional materials from scanning tunneling microscopy/spectroscopy (STM/STS) measurements. When the charge order pr…
Superfluid stiffness of a KTaO3-based two-dimensional electron gas
S. Mallik, G. Ménard, G. Saïz +6
After almost twenty years of intense work on the celebrated LaAlO3/SrTiO3 system, the recent discovery of a superconducting two-dimensional electron gases (2-DEG) in (111)-oriented…
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…
Chiral spin texture in the charge-density-wave phase of the correlated metallic Pb/Si(111) monolayer
C. Tresca, C. Brun, T. Bilgeri +10
We investigate the 1/3 monolayer -Pb/Si(111) surface by scanning tunneling spectroscopy (STS) and fully relativistic first-principles calculations. We study both the high-temper…
Two-dimensional topological superconductivity in Pb/Co/Si(111)
Gerbold C. Ménard, Sébastien Guissart, Christophe Brun +7
Just like insulators can host topological Dirac states at their edges, superconductors can also exhibit topological phases characterized by Majorana edge states. Remarkable zero-en…
Proximity effect between two superconductors spatially resolved by scanning tunneling spectroscopy
V. Cherkez, J. C. Cuevas, C. Brun +5
We present a combined experimental and theoretical study of the proximity effect in an atomic-scale controlled junction between two different superconductors. Elaborated on a Si(11…
