Research interests

Keywords: strongly correlated systems, one-dimensional systems, topological isolators, Monte Carlo algorithms, neural networks

My research interests encompass several areas: (i) Strongly correlated electron, electron-phonon and boson systems. In two and three dimensions such systems often exhibit exotic superconductivity, charge and magnetic orderings, and interplay of those. One of the examples are high-Tc cuprate superconductors. (ii) One-dimensional systems have unique properties described by Luttinger liquid, spin-charge separation, etc. Domain-wall type excitations (i.e. spinons) frequently carry fractional spin or charge. Strong correlations often lead to fractional exclusion statistics or string (hidden) order.  Interestingly many models can be exactly solved, I’m author of one of such solutions. (iii) Statistical physics, numerical complexity theory and neural networks are deeply connected areas. I develop new methods and Monte Carlo algorithms, motivated by statistical physics, for physical and neural networks models.
