Research Experience

I started with PT-symmetric quantum systems incorporating supersymmetric techniques and mean-field models for cold atoms. Then I worked in non-perturbative Topological Gauge theories, Extended Effective Gravity, and Effective Models of Fermion Conductivity.  Currently, I am studying Deformed Integrable Models and PT-symmetric Field Theories. My immediate research interests are:

  • Quantum corrections and anomalies in PT-symmetric systems
  • Gauge theories with topological terms
  • Deformed integrable models with localized solutions
