Non-equilibrium quantum materials

Our research focuses on theoretical and computational nanophysics. With many-body quantum theory, we study the out-of-equilibrium dynamics of electrons and bosons at small length and short time scales, approximately nanometer and femtosecond orders of magnitude. The goal is to understand the microscopic nature of correlated quantum systems, potentially utilized in next-generation nano- and quantum technologies.

Our research focuses on theoretical and computational nanophysics. With many-body quantum theory, we study the out-of-equilibrium dynamics of electrons and bosons at small length and short time scales, approximately nanometer and femtosecond orders of magnitude. The goal is to understand the microscopic nature of correlated quantum systems, potentially utilized in next-generation nano- and quantum technologies.
