Diode effect in Josephson junctions with a single magnetic atom
Martina Trahms, Larissa Melischek, Jacob F. Steiner +8
Current flow in electronic devices can be asymmetric with bias direction, a phenomenon underlying the utility of diodes and known as non-reciprocal charge transport. The promise of…
Direct observation of intrinsic surface magnetic disorder in amorphous superconducting films
Idan Tamir, Martina Trahms, Franzisca Gorniaczyk +3
The interplay between disorder and interactions can dramatically influence the physical properties of thin-film superconductors. In the most extreme case, strong disorder is able t…
Shot-noise measurements of single-atom junctions
Idan Tamir, Verena Caspari, Daniela Rolf +2
Current fluctuations related to the discreteness of charge passing through small constrictions are termed shot noise. This unavoidable noise provides both advantages - being a dire…
Limited role of vortices in transport in highly disordered superconductors near
Adam Doron, Tal Levinson, Franzisca Gorniaczyk +2
At finite temperatures and magnetic fields, type-II superconductors in the mixed state have a non-zero resistance that is overwhelmingly associated with vortex motion. In this work…
The Critical Current of Disordered Superconductors near T=0
Adam Doron, Tal Levinson, Franzisca Gorniaczyk +2
An increasing current through a superconductor can result in a discontinuous increase in the differential resistance at the critical current. This critical current is typically ass…
Excessive Noise as a Test for Many-Body Localization
I. Tamir, T. Levinson, F. Gorniaczyk +3
Recent experimental reports suggested the existence of a finite-temperature insulator in the vicinity of the superconductor-insulator transition. The rapid decay of conductivity ov…
The Temperature dependence of the magneto-resistance peak in highly disordered superconductors
Adam Doron, Idan Tamir, Tal Levinson +2
Highly disordered superconductors have a rich phase diagram. At a moderate magnetic field (B) the samples go through the superconductor-insulator quantum phase transition. In the i…
Extreme Sensitivity of the Superconducting State in Thin Films
I. Tamir, A. Benyamini, E. J. Telford +12
All non-interacting two-dimensional electronic systems are expected to exhibit an insulating ground state. This conspicuous absence of the metallic phase has been challenged only i…
Absence of cyclotron resonance in the anomalous metallic phase in InO
Youcheng Wang, Idan Tamir, Dan Shahar +1
It is observed that many thin superconducting films with not too high disorder level (generally R) placed in magnetic field show an anomalous metallic phase wh…
Non-equilibrium restoration of duality symmetry in the vicinity of the superconductor-insulator transition
I. Tamir, A. Doron, T. Levinson +3
The magnetic field driven superconductor to insulator transition in thin films was theoretically analyzed via a vortex-charge duality transformation applied to the Hamiltonian. Vor…
A Direct Determination of the Temperature of Overheated Electrons in an Insulator
Tal Levinson, Adam Doron, Idan Tamir +2
Highly disordered superconductors, in the magnetic-field-driven insulating state, can show discontinuous current-voltage characteristics. Electron overheating has been shown to giv…
Instability of insulators near quantum phase transitions
Adam Doron, Idan Tamir, Tal Levinson +3
Thin films of Amorphous indium oxide undergo a magnetic field driven superconducting to insulator quantum phase transition. In the insulating phase, the current-voltage characteris…
High field termination of a Cooper-pair insulator
B. Sacepe, J. Seidemann, M. Ovadia +5
We conducted a systematic study of the disorder dependence of the termination of superconductivity, at high magnetic fields (B), of amorphous indium oxide films. Our lower disorder…
Evidence for a Finite Temperature Insulator
M. Ovadia, D. Kalok, I. Tamir +3
In superconductors the zero-resistance current-flow is protected from dissipation at finite temperatures (T) by virtue of the short-circuit condition maintained by the electrons th…
