REsearch activities

My primary research interest is to understand the fundamental interactions of nature via analytic and computational methods. My current research focuses on understanding the strong interaction of nature described by quantum chromodynamics by simulating the same on a quantum computer as the technology emerges. 

My research career started with contributing to the development of the prepotential formulation of lattice gauge theories which is a novel reformulation of the original Kogut-Susskind formulation of Hamiltonian lattice gauge theories in terms of the Schwinger boson representation of the Lie algebra corresponding to the gauge symmetry. The Prepotential framework allows one to define and work with site-local gauge invariant variables that correspond to local loop degrees of freedom yet allows one to solve all the get rid of all gauge redundancy as well as overcompleteness of loop basis. Coupling prepotentials with dynamical staggered fermions leads to a complete and novel framework of Hamiltonian lattice gauge theories, named as the loop string hadron formulation. 

The loop-string-hadron framework is found to be one of the most convenient frameworks for quantum-simulating non-Abelian lattice gauge theories and the same is currently being pursued for developing analog and digital quantum simulation algorithms as well as state-of-the-art Hamiltonian simulation algorithms using a classical computer using tensor network methods.  

My research also focusses on studying other strongly correlated systems of nature using analytic and computational tools for simpler models and understanding interesting physics including its topological properties.

My publications can be found in Google-Scholar or Inspire-hep.
