Opis

These proceedings of the NATO-ARW "Electron transport in nanosystems" held at the "Russia" Hotel, Yalta, Ukraine from 17-21 September 2007 resulted in many discussions between various speakers. The wide range of topics discussed at the Yalta NATO meeting included the new nanodevice applications, novel materials, superconductivity and s- sors. There have been many signi?cant advances in the past 2 years and some entirely new directions of research in these ?elds are just opening up. Recent advances in nanoscience have demonstrated that fundamentally new phy- cal phenomena are found when systems are reduced in size with dimensions, comparable to the fundamental microscopic length scales of the investigated material. Late developments in nanotechnology and measurement techniques now allow experimental investigation of transport properties of nanodevices. Great interest in this research is focused on development of spintronics, molecular electronics and quantum information processing and graphene. At the workshop, important open problems concerning cuprate superconductity, mesoscopic superconductors and novel superconductors such MgB, CeCoIn 2 5 whereconsidered.Therewasmuchdiscussionofthemechanismandsymmetry of pairing for cuprate superconductorsas well as the nature of the pseudogap. In the sessiononnovelsuperconductors, the physicalproperties of MgB were 2 discussed. There were also lively debates about two-gap superconductivity in MgB .
