The Kondo effect is an unusual scattering mechanism of conduction electrons in a metal due to magnetic impurities, which contributes a term to the electrical resistivity that increases logarithmically with temperature as the temperature T is lowered as log(T) (Scholarpedia).

Real quantum systems are never completely isolated. They interaction with environment leads to quantum dissipation and quantum decoherence. Both this effects present conceptual and technical challenges with implications for different areas of physics and technology including quantum computing and nano-science.

The advent of new technologies made possible study of electronic transport through quantum objects like single molecules, molecular wires, and quantum dots. The research of quantum transport opens new ways of understanding quantum-mechanical behaviour of strongly correlated systems.

A stochastic dynamical system is a dynamical system subjected to the effects of noise (Scholarpedia).

In our group we study both classical and quantum dynamical systems. We focus on bistability and switching in stochastic dynamical system as well as on stochastic termodynamics.

Superconducting quantum dot consists of a quantum dot, a device that allows to store and manipulate single electrons, and superconducting leads, where superconductivity is a macroscopic quantum phenomena.

Superconducting quantum dots are rich physical playgrounds with tremendous potential for real world applications. Our primarily effort is focused on making the theoretical analyses of real superconducting quantum dots as easy as possible.

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature (Wikipedia).

In our group we focus on superconductive electron transport through nanoscale objects like Josephson junctions or superconductive quantum dots.
