Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We consider the charge and spin effects in low dimensional superconducting weak links. The first
part of the review deals with the effects of electron—electron interaction in Superconductor/
Luttinger liquid/Superconductor junctions. The experimental realization of this mesoscopic hybrid
system can be the individual single wall carbon nanotube that bridges the gap between two bulk
superconductors. The dc Josephson current through a Luttinger liquid is evaluated in the limits of perfectly
and poorly transmitting junctions. The relationship between the Josephson effect in a long SNS
junction and the Casimir effect is discussed. In the second part of the paper we review the recent results
concerning the influence of the Zeeman and Rashba interactions on the thermodynamical properties
of ballistic S–QW–S junction fabricated in two dimensional electron gas. It is shown that in magnetically
controlled junction there are conditions for resonant Cooper pair transition which results in
giant supercurrent through a tunnel junction and a giant magnetic response of a multichannel SNS
junction. The supercurrent induced by the joint action of the Zeeman and Rashba interactions in 1D
quantum wires connected to bulk superconductors is predicted. |
