Research Overview
Optoelectronic and mechanical properties of quantum materials, van der Waals heterostructures, engineering light-matter interactions, ultrafast optical and THz spectroscopy, coherent control of material properties
Our research goal is to understand how light-matter and matter-matter interactions lead to emergent optoelectronic and mechanical properties of low-dimensional quantum materials. We use various optical spectroscopic techniques to (1) study the ultrafast dynamics of electrons, atoms, and quasiparticles, (2) probe the fundamental interactions between them and induce strong interactions, 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 control the material properties, opening new pathways to enable fast and efficient optoelectronic devices.
