Giant oscillations of the density of states and the conductance in a ferromagnetic conductor coupled to two superconductors
A. Kadigrobov, R. I. Shekhter, M. Jonson
Giant oscillations of the density of electronic states and the differential conductance of a superconductor-ferromagnet-superconductor structure are predicted for the case when the…
Single-interface superconductivity in two-layer semiconductor heterostructures
N. Ya. Fogel, E. I. Buchstab, Yu. V. Bomze +6
We have discovered superconductivity in the two-layer semiconducting monochalcogenide heterostrutures PbTe/PbS, PbTe/PbSe and PbTe/YbS. By comparing data from two-layer samples wit…
Internal and interfacial friction in the dynamics of soft/solid interfaces
M. V. Voinova, M. Jonson, B. Kasemo
We analyze theoretically the effect of friction on quartz crystal microbalance (QCM) measurements that probe soft (viscoelastic) films and biomolecular layers adsorbed from aqueous…
Microwave controlled phase coherent transport in mesoscopic S-N-S structures
N. I. Lundin, L. Y. Gorelik, R. I. Shekhter +2
We show that transport through a superconducting quantum point contact biased at subgap voltages is strongly affected by a microwave field. The subgap current is increased by sever…
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…
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…
