TQCM-Topological Quantum Condensed Matter

 

Research Interests:

I am interested in various topics in theoretical condensed matter physics, like

  • Quantum Hall Effect
  • Mesoscopic Physics
  • Topological Insulator
  • Quantum Magnets
  • Weyl Semimetals
  • Topological classification of band degeneracies
  • Quantum Hall Interface
  • Graphene and its electronic properties
  • Renormalization Group.

I use both analytical and numerical methods to investigate questions related to the these topics.
