The aim of this website to introduce you to our group and the work we do.
Our group's research is focused on various aspects of light-matter interactions with complex systems.
The photonics part of our research activities is concentrated in two aspects. First, we are interested in studies of the thermodynamics of small systems, where quantum effects start playing an important role. Our newly developed methods allow to optimize performance of light generation and harvesting devices as well as optimize optical spectroscopy outputs. Second, we would like to investigate topological effects on generation and control of the light. 2D artificial materials can serve as a novel platform for investigation of material properties in highly topological quantum regime as well as the sources of quantum light.
The complex system part is related to ultrafast spectroscopic studies with both: weak quantum light and in strong high harmonic regime. First, the main focus of quantum optics is on nonclassical light interacting with rather simple qubit system. In the same time nonlinear optical spectroscopy is based on studies of the complex system with classical light. We combine both approaches by developing a new methods of spectroscopic studies based on nonclassical light. Second, the high harmonic generation sources require strong laser fields. However, under certain condition, one can treat part of the process perturbatively as it is done in classical light spectroscopy. We can therefore predict novel nonlinear optical signals and develop novel methods for ultrafast electron dynamical studies on a multi-eV energy scale with IR/visible light sources.
