About Me

Research

I am a theoretical physicist with research interests that overlap Condensed Matter and Nonlinear dynamics. Some of the topics of current interest include quantum phase transitions, topological aspect of quasiperiodic and periodically driven lattices, solitary waves in Bose-Einstein condensate, Hanbury Brown-twiss effect and Abelian and non-Abelian gauge Fields.
