Strong Light-Matter Coupling in 2D Atomic Crystals


Vinod Menon (City University of New York)


Alexey Belyanin

Event Details

Two-dimensional (2D) van der Waals materials have emerged as a very attractive class of optoelectronic material due to the unprecedented strength in its interaction with light. In this talk I will first discuss the formation of exciton-polaritons [1] and their spin-optic control [2, 3] in the 2D transition metal dichacogenide (TMD) systems. Following this, I will discuss the formation of polaritons using excited states (Rydberg states) to enhance the nonlinear polariton interaction [4]. Recent results on realization of a polariton LED based on 2D TMDs [5] and control of valley coherence using pseudomagnetic fields in microcavities will also be presented.
