The low-energy states of two-dimensional hole gases formed in transition metal dichalcogenide heterobilayer moiré superlattices are accurately described by two-dimensional triangular-lattice Hubbard models.  I will discuss progress that has been made in exploring the properties of these systems both theoretically and experimentally.  

 

 

 

 

The ability to probe and control photon at the nanometer scale not only advances frontiers of fundamental science, but also provides critical prerequisites to applications in imaging, sensing, catalysis, energy harvesting, and more. Exploiting and enhancing the originally weak light-matter interactions via novel photonic structures, we will be able to sense chemical species at single molecule levels, to devise better imaging tools, to transfer data more efficiently at higher speed.
