Mesoscopic Physics

This field deals with systems of "mesoscopic" (intermediate) scales, typically of submicron dimensions. Both metallic, semiconducting and superconducting systems of that size exhibit unusual features, involving novel physical effects. Over the past 15 years a number of such effects have been predicted theoretically and measured exprimentally. The main message to emerge from all these studies is that when it comes to mesoscopic scales, common wisdom has to be revised, i.e. the 'rules of the game' concerning textbook electronics have to be rewritten. From the more applied point-of-view this field constitutes the basis for future micro- and nano-electronics.

Specific problems that I have been working on include: persistent currents and anomalous magnetism in small conductors; the physics of 'quantum dots', including the interplay between disorder and strong correlations due to electron-electron interactions;the Quantum Hall Effect (and particularly the Fractional Quantum Hall Effect) in restricted geometries.
