Spectroscopy of Quasi-Particles (SQUAP)

The SQUAP team is interested in the physics of interacting electrons in quantum materials, which leads to the emergence of unusual electronic and topological orders that coexist and, in some cases, compete, providing a fertile playground to study quantum phases and electron correlations in materials. To study these quantum materials, we mainly use static and time-resolved Raman and THz spectroscopies. A unique feature of the team is to combine spectroscopic tools with static tuning parameters such as low/high temperatures, pressure and magnetic field, but also dynamical ones like ultrashort light pulses.
