Research Overview
Optoelectronic and mechanical properties of quantum materials, van der Waals heterostructures, engineering light-matter interactions, ultrafast optical and THz spectroscopy, THz-induced phenomena, coherent control of material properties
Our research goal is to understand how light-matter and matter-matter interactions lead to emergent optoelectronic and quantum-mechanical properties of low-dimensional quantum materials. We use various ultrafast spectroscopic techniques from visible to THz frequencies to (1) study the ultrafast dynamics of electrons, atoms, and quasiparticles in solids, (2) probe the fundamental and light-induced interactions between them, and (3) monitor their transport across different layers or nano-domains such as moiré superlattice sites in van der Waals heterostructures. Furthermore, we use strong electromagnetic fields in and out of a photonic cavity to coherently control material properties and to create strong correlations, opening new pathways to enable fast and efficient optoelectronic and quantum photonic devices.
