Strongly Correlated Low-Dimensional Electron Systems

The current research area includes quantum transport phenomena in low-dimensional electron systems with extremely strong internal interactions. The central objects of interest are the Coulomb liquid, of which the average Coulomb interaction energy per electron is much higher than the mean kinetic energy, and the Wigner solid. The important research themes are the unconventional Hall effect in two-dimensional (2D) electron liquids, quantum cyclotron resonance and dynamics of highly correlated electrons strongly coupled with medium excitations. The most popular experimental realizations of such systems, which possess remarkable properties, are the 2D Coulomb liquid and Wigner solid formed on the free surface of liquid helium and other cryogenic interfaces. An instructive result of these studies is that the relationship and similarity between a strongly correlated electron liquid and an ideal gas can be established not for the excitation spectrums, but for a more global property, the dynamical structure factor, which plays an important role in the quantum transport theory of highly correlated electrons. In 2012, this result was successfully applied for description of Coulombic effects on microwave-induced magnetoconductivity oscillations of surface electrons on liquid helium.
