Giant conductance oscillations in a normal mesoscopic ring induced by an SNS Josephson current
A. Kadigrobov, A. Zagoskin, R. I. Shekhter +1
A theoretical explanation of giant conductance oscillations observed in normal mesoscopic rings with superconducting ``mirrors" is proposed. The effect is due to resonant tuning of…
Influence of Long-Range Coulomb Interactions on the Metal-Insulator Transition in One-Dimensional Strongly Correlated Electron Systems
I. V. Krive, A. A. Nersesyan, M. Jonson +1
The influence of long-range Coulomb interactions on the properties of one-dimensional (1D) strongly correlated electron systems in vicinity of the metal-insulator phase transition…
Persistent Current of a One-Dimensional Wigner Crystal-Ring
I. V. Krive, R. I. Shekhter, S. M. Girvin +1
We calculate the magnetic moment (`persistent current') in a strongly correlated electron system --- a Wigner crystal --- in a one-dimensional ballistic ring. The flux- and tempera…
Spectroscopy of the Potential Profile in a Ballistic Quantum Constriction
I. E. Aronov, M. Jonson, A. M. Zagoskin
We present a theory for the nonlinear current-voltage characteristics of a ballistic quantum constriction. Nonlinear features first develop because of above-barrier reflection from…
