Research interests

Keywords: spintronics, quantum transport, strong electron correlations, quantum dots and molecules, renormalization group methods, Kondo effect, Majorana fermions

In brief, my research interests encompass studies of various properties of nanostructures, ranging from 0D (e.g. quantum dots and molecules), through 1D (e.g. quantum wires) to 2D (e.g. nanostructured graphene) systems. I focus especially on strong electron correlations, which can give rise to various interesting effects, such as the Kondo effect. I also study topological aspects of quantum matter, in which e.g. Majorana quasiparicles can emerge. Another part of my research is associated with the development of modern numerical tools for the studies of properties of nanostructures. I am the coauthor of the open-access Flexible DM-NRG code for studying the transport properties of nanostructures based on the renormalization group methods. My works contribute to the development of the theoretical foundations and understanding of solid state physics, especially, quantum transport, spin nanoelectronics, molecular spintronics and spin caloritronics.
