Persistent current and persistent charge in nanostructures

Abstract

Quantúm effects in the interaction of electromagnetic field with small, but not microscopically small, metallic particles and rings are investigated. The aspects of mesoscopic systems related to time-independent (or magnetic) Aharonov-Bohm effect, time-dependent (electric) Aharonov-Bohm effect, and to quantum high-frequency effects in a coupled system: optical fiber+ mesoscopic conducting loop are discussed.
