SUMMARY:Control of Light-Matter Interactions in 2D Materials - Professor V

DESCRIPTION: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 discuss appro
 aches to enhance and control this interaction by integrating these 2D mate
 rials with microcavities\, and metamaterials. I will first discuss the for
 mation of strongly coupled half-light half matter quasiparticles (microcav
 ity polaritons) [1] and their spin-optic control [2] in the 2D transition 
 metal dichacogenide (TMD) systems. Following this I will discuss the forma
 tion of polaritons using excited states (Rydberg states) to enhance the no
 nlinear polariton interaction. Recent results on electrical control [3] an
 d realization of a polariton LED based on 2D TMDs will also be presented. 
 Finally\, I will briefly talk about room temperature single photon emissio
 n from hexagonal boron nitride [4] and the prospects of developing determi
 nistic quantum emitters using them [5].\n\nReferences\n[1] X. Liu\, et al.
