Localization of preformed Cooper pairs in disordered superconductors
Benjamin Sacépé,Benjamin Sacépé,Thomas Dubouchet,Claude Chapelier,Marc Sanquer,M. Ovadia,Dan Shahar,Mikhail Feigel'man,Lev Ioffe +8 more
TL;DR: In a superconductor, the electrons are paired up and scanning tunnelling microscopy shows that the pairs localize together rather than breaking up and forming localized single electrons in the insulating state as discussed by the authors.

Evidence for a Finite Temperature Insulator
M. Ovadia,D. Kalok,I. Tamir,Sreemanta Mitra,Benjamin Sacépé,Benjamin Sacépé,Benjamin Sacépé,Dan Shahar +7 more
TL;DR: In this article, the authors show that the conductivity of the high magnetic-field terminating superconductivity in amorphous indium-oxide exhibits an abrupt drop, and seem to approach a zero conductance at T < 0.04
Evidence for a Finite Temperature Insulator
M. Ovadia,D. Kalok,I. Tamir,Sreemanta Mitra,Benjamin Sacépé,Benjamin Sacépé,Benjamin Sacépé,Dan Shahar +7 more
TL;DR: It is shown that the conductivity of the high magnetic-field insulator terminating superconductivity in amorphous indium-oxide exhibits an abrupt drop, and seem to approach a zero conductance at T < 0.04 K.
Duality symmetry and its breakdown in the vicinity of the superconductor-insulator transition
TL;DR: In this paper, the magnetic-field-induced superconductor-insulator transition was studied and it was shown that the insulating state is the electromagnetic dual of the superconducting state.
Low-temperature anomaly in disordered superconductors near B c2 as a vortex-glass property
Benjamin Sacépé,Johanna Seidemann,Kevin Davenport,Andrey Rogachev,M. Ovadia,Karen Michaeli,Mikhail Feigel'man,Mikhail Feigel'man +7 more
TL;DR: Systematic measurements of the critical magnetic field and current on amorphous indium oxide films with various levels of disorder show that the Bc2 anomaly is accompanied by mean-field-like scaling of thecritical current, and theory predicts that the linear-temperature anomaly occurs more generally in both films and disordered bulk superconductors.
