Ultrafast dynamics of photoexcited quantum materials is a interdisciplinary area, which offers unique opportunities for development of new devices. We have expertise in application of femtosecond techniques to study non-equilibrium condensed phase processes. The attosecond XUV pulses open up new avenues by allowing creation of multiple excitations within short temporal duration, thus providing a unique starting point for observation of many-particle correlation effects.

Our latest work measures the electron and phonon dynamics in graphene-hBN heterostuctures and the effect of isotopic composition of Boron in hBN on the heat diffusion through the graphene-hBN interface. We have also studied defects and phonons in WSe2.
