Current Research

Strongly correlated electronic systems

My research explores the intriguing interplay of energetics and topology on strongly interacting electrons. Current directions include:

  • realization of non-abelian fractional quantum Hall (FQH) states
  • holography and conformal field theory
  • fractional Chern insulators and anisotropic FQH
  • out-of-equilbrium (Floquet) studies

Topological metamaterials and classical realizations

I am also interested in realizing topological states beyond electronic systems. In various classical systems, the effects of topology can be exploited for novel technological applications. Specific directions include:

  • topological circuits and their robust electrical resonances
  • topological photonics
  • topological mechanics
  • Floquet topological metamaterials
