Spectroscopy techniques provide a powerful tool to directly probe fundamental interactions between the constituents of matter. We employ and develop state-of-the-art theoretical approaches to complement experimental investigations and predict, in silico, novel emergent phenomena in spectroscopy.
The interplay of electrons, crystal-lattice vibrations (phonons), and collective charge-density fluctuations (plasmons) underpins a vast spectrum of physical phenomena in condensed matter. Starting from the fundamental equations of quantum mechanics, we develop new ab-initio theories and computational techniques for investigating fundamental interactions (as, e.g., the electron-phonon and electron-plasmon interactions) and their influence on the opto-electronic properties of quantum materials.

The advent of ultra-short light pulses has enabled the exploration of non-equilibrium phenomena at the characteristic timescales at which electrons and ions move. Part of our research is devoted to the theoretical investigation of the ultra-fast dynamics of electrons and phonons driven out of equilibrium by the interactions with ultra-short light pulses.
