"The main goal of our group is the optical manipulation of spin and charge excitations (magnons, excitons, plasmons) in two-dimensional electronic systems on the shortest possible, typically femtosecond (10-15s), time scale. To achieve this goal we implement experimental pump-probe methods based on magneto-optical spectroscopy and spin-resolved ARPES (angle-resolved photoelectron spectroscopy). The spectroscopic experiments are performed using pulsed femtosecond radiation in a very wide photon energy range from the infrared to the extreme ultraviolet (approximately from 0.1 eV to 70 eV).
Currently, the following material systems are mainly studied: spin-textured and magnetically ordered two-dimensional electronic systems (2D semiconductors, 2D antiferromagnets, topological insulators, quantum wells, ...), as well as hybrid molecular interfaces with non-trivial spin properties (so-called molecular spin interfaces)."
![Band structure of 2D semimetal based on HgTe quantum well. Experimental points are obtained from the analysis of the cyclotron resonance in the quasi-classical approximation. Solid lines are predictions of the kp theory with no free parameters. Splitting of the conduction (e1,2) and valence (h1) band is due to the quantum confinement. [J.
