Dear Colleagues, 

On Monday, the BME Exotic Quantum Phases seminar continues with this talk:

  You Zhou (Maryland)
  Excitons in twisted flatland

online in Teams
Time: May 10, Monday, 14:15

Abstract: Atomically thin transition metal dichalcogenides (TMDs) have 
attracted recent interest due to their unique excitonic properties. Lateral 
confinement of excitons to generate two-dimensional exciton arrays may open 
up new avenues for quantum optoelectronics such as topological photonics and 
quantum emitter arrays. Realizing such emitter arrays, however, requires the 
development of new methods to engineer the excitonic energy landscape at the 
nanoscale. In this talk, I will focus on how to use twisted TMD bilayers to 
engineer the coherence and relaxation properties of excitons. I will discuss 
lattice reconstruction effects in the moiré pattern and correlating their 
importance in determining the excitonic behaviors. Finally I will discuss 
prospects of realizing tunable exciton arrays in twisted heterostructures for 
exploring novel optoelectronics and many-body states.

About the speaker: Dr. You Zhou is an Assistant Professor at the University 
of Maryland, College Park. He was a postdoctoral fellow in Prof. Hongkun 
Park’s group at Harvard University between 2015 and 2020. He earned his Ph.D. 
in Applied Physics from Harvard in 2015, studying under Prof. Shriram 
Ramanathan, after receiving his bachelor’s degree in Physics from Peking 
University in 2010.
