My research studies miniature electronic systems, where quantum mechanical effects qualitatively alter observable physical properties. These so called mesoscopic systems are positioned somewhere between an atomic scale and a human scale, having sizes ranging between tens of nanometers and microns. Mesoscopic systems exhibit all of textbook single particle quantum phenomena. However, while being essentially quantum, these systems consist of macroscopic numbers of particles, which makes quantum phenomena substantially more rich and interesting. Currently I am working on the following topics: (a) quantum transport in low-dimensional electronic systems, such as quantum dots and nanotubes; (b) physics of a recently discovered two-dimensional material, graphene, with an emphasis on quantum Hall effect; (c) quantum Hall ferromagnetism; (d) non-equilibrium phenomena, which occur when electrons are driven out of equilibrium, or when
system parameters are deliberately varied in time (many-body generalizations of Landau-Zener problem); (e) topological insulators and their experimental signatures; (f) spin-Hall effects.
