Main Nano Field: Ultrafast light-matter interactions in 2D materials, material surfaces and interfaces, and light-induced charge motion in molecular systems.

 

Research interests: We study theory of ultrafast light-matter interactions and quantum dynamics in multidisciplinary complex systems, with a particular emphasis on novel quantum materials (2D materials, topological solids, magnetic systems) and molecules, as well as interfaces between systems and phases. Our focus is fundamentally understanding femtosecond to attosecond timescale coherent dynamics that arise when matter is irradiated by intense laser pulses, including high harmonic generation (HHG), photocurrent generation, light-dressed phases, ultrafast magnetism, charge migration, and more. In such conditions, physical processes are highly nonlinear and perturbation theory breaks down, posing challenges for theory, and opportunities for uncovering new effects. We also actively develop new methods for time-resolved spectroscopy and novel light sources such as ultrashort magnetic pulses. We use diverse tools ranging from analytic approaches, numerical models, and ab-initio simulations such as real-time time-dependent density functional theory (TDDFT).
