Journal ArticleDOI
Two-dimensional topological superconductivity in Pb/Co/Si(111)
Gerbold Menard,Sébastien Guissart,Christophe Brun,Raphaël T. Leriche,Mircea Trif,François Debontridder,Dominique Demaille,Dimitri Roditchev,Dimitri Roditchev,Pascal Simon,Tristan Cren +10 more
TL;DR: The measured dispersive in-gap states are interpreted as a spatial topological transition with a gap closure and could in principle be generalized to a large variety of heterostructures combining a Rashba superconductor with a magnetic layer in order to be used as a platform for engineering topological quantum phases.
Journal ArticleDOI
Coherent long-range magnetic bound states in a superconductor
Gerbold Menard,Sébastien Guissart,Christophe Brun,Stéphane Pons,Stéphane Pons,Vasily S. Stolyarov,Vasily S. Stolyarov,François Debontridder,Matthieu V. Leclerc,Etienne Janod,Laurent Cario,Dimitri Roditchev,Dimitri Roditchev,Pascal Simon,Tristan Cren +14 more
TL;DR: Magnetic atoms embedded in a niobium selenide superconductor were shown to give rise to a long-range coherent bound state extending tens of nanometres.
Journal ArticleDOI
Two-dimensional topological superconductivity in Pb/Co/Si(111)
Gerbold Menard,Sébastien Guissart,Christophe Brun,Mircea Trif,François Debontridder,Raphël T. Leriche,Dominique Demaille,Dimitri Roditchev,Pascal Simon,Tristan Cren +9 more
TL;DR: In this article, the dispersive in-gap states surrounding topological superconducting domains made of a single atomic layer of Pb covering magnetic islands of Co/Si(111) were observed.
Journal ArticleDOI
Conductance-Matrix Symmetries of a Three-Terminal Hybrid Device.
Gerbold Menard,G. L. R. Anselmetti,Esteban Martínez,Denise Puglia,Filip K. Malinowski,Joon Sue Lee,Sukgeun Choi,Mihir Pendharkar,Chris Palmstrom,Karsten Flensberg,Charles Marcus,Lucas Casparis,Andrew Higginbotham +12 more
TL;DR: In this paper, a three-terminal superconductor-semiconductor hybrid device consisting of two normal leads and one superconducting lead is analyzed using a symmetry decomposition of the conductance.
Journal ArticleDOI
Closing of the induced gap in a hybrid superconductor-semiconductor nanowire
Denise Puglia,Denise Puglia,Esteban Martínez,Gerbold Menard,A. Pöschl,Sergei Gronin,Geoffrey C. Gardner,Ray Kallaher,Michael J. Manfra,Charles Marcus,Andrew Higginbotham,Andrew Higginbotham,Lucas Casparis +12 more
TL;DR: In this article, conductance-matrix measurements in long, three-terminal hybrid superconductor-semiconductor nanowires were performed and compared with theoretical predictions of a magnetic-field-driven, topological quantum phase transition.
