Research interests are focused on electron transport in  low dimensional  systems at low temperatures. The studied systems include high quality 2D electron systems, atomically thin superconducting films and 3D topological insulators.   His research team investigates effects of quantum mechanics on the electron transport, in particular, how quantum mechanical properties  of matter affect dissipation of the electric energy. 

One of the main developments of Sergey Vitkalov and his collaborators is the concept of quantal heating of the electrons in  two-dimensional electron systems with a quantized energy spectrum. This effect stands distinctly apart from usual Joule heating. Quantal heating is absent in classical systems. The heating produces a peculiar spectral distribution of electrons, which cannot be described by a temperature. It results in significant reduction of the electric energy dissipation in conductors with quantized energy spectrum.  The research is supported by National Science Foundation.
