The Ju Lab
Nano Optics for Quantum Materials
Welcome to Long Ju's group in the physics department at MIT! Our research focuses on understanding light-matter interactions in novel quantum materials. Of particular interest are atomically thin materials and van der Waals hetero-structures of them. These materials host a variety of fascinating electronic and optical properties individually, and they offer exciting opportunities to explore possibilities enabled by controlling the stacking order and electrically tuning the band structure and charge doping. Especially, such materials provide a new platform to design and engineer more exotic quantum phenomena when electron correlations and topology are included. See Research for more details.
