About My Work

I have a diverse range of research interests in theoretical condensed matter physics, however my main topic of interest is, from a broad point of view, the understanding of effects of many body correlations in cold atoms and condensed matter systems. Collective phenomena reveal themselves in the strongest way in low dimensional systems. They have been the subject of my research lately.
