 Education

  • 2009-2015: Ph.D. in Quantum Field Theory from Indian Institute for Science Education and Research Kolkata, India. Supervisor: Dr. Prasanta K Panigrahi.
  • 2004-2005: MSc in Physics from Dibrugarh University, Assam, India.
  • 2000-2003: BSc in Physics (Hons.) from Jagannath Barooah College under Dibrugarh University, Assam, India.

 

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

 

Refereeing service

  • Annals of Physics
  • Classical and Quantum Gravity
  • Journal of Physics Communication
