My research interests are in an area of theoretical condensed matter
physics of disordered and strongly-correlated, mostly low-dimensional
systems. This includes two-dimensional electron systems (2DES's) in
semiconductors and on the surface of liquid Helium, both in zero
magnetic field and under the conditions of quantum Hall effect,
layered high-transition temperature (high-Tc) cuprate superconductors
and related materials, various one-dimensional systems (self-organized
quasi-1D systems like stripes in cuprates, chiral edge channels in
quantum Hall samples, quasi-one-dimensional organics, carbon
nanotubes, etc), ``zero''-dimensional systems (quantum dots, tunneling
junctions, Kondo spins, etc).
This field is an active, mathematically advanced,
intellectually-gratifying area of research on the very frontier of
science, competitive and extremely attractive to aspiring scientists.
It rapidly gains in importance because of the interest in novel
materials with unusual properties, as a natural result of the
technological development towards nano-scale electronics, and in
relation to the quantum computing effort.
