Current Research

Synthetic and non-equilibrium topological matter

Topological signatures are widespread in various synthetic topological metamaterials and non-equilibrium setups, with potential applications in photonics and electronics. My specific directions include:

  • topological circuits and their robust topolectrical resonances
  • non-Hermitian and Floquet dynamics
  • topological photonics and mechanics
  • topology of non-linear dynamics

Strongly correlated electronic systems

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

  • realization of non-abelian fractional quantum Hall (FQH) states
  • topological quantum computing
  • holography and conformal field theory
  • fractional Chern insulators
