Research interests
Theoretical investigation of solid-state non-amorphous materials, including low-dimensional (2D, 1D, 0D) materials.The current research is devoted to the investigation of strongly-correlated systems in the framework of the dynamical mean-field theory with particular attention to charge order and transitions between different charge-ordered phases and phases without charge order, including Fermi-liquid phase and Mott insulator.The previous experience encompasses the ab-initio investigation by means of the density-functional theory of 3D, 2D and 1D materials, focusing on their electron and phonon properties, their stability and transitions between them (3D to thin film, thin film to monolayer, monolayer to nanotube), and low-dimensional effects.
