About me
I am a theoretical physicist working as an assistant professor at BITS Pilani, Goa Campus in India since August 2021. I have completed my PhD in 2014 from SN Bose National Center for Basic Sciences, Kolkata. Afterwards I gained post doctoral research experience at the Institute of Mathematical Sciences, Chennai, the Indian Association for Cultivation of Science, Kolkata, and the University of Maryland, College Park, Maryland, USA.
My detailed CV can be found here.
I'm moderately active on social media via LinkedIn and Facebook.
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.
My Research group at BITS Pilani Goa Campus
Emil joined the PhD program in October 2021, soon after I joined as a faculty. Emil is currently developing tensor network ansatz for loop-string-hadron and benchmarking the dynamics of the theory. Emil has also developed useful symmetry protection schemes for SU(2) and SU(3) gauge theories for quantum simulating the same.
Aahiri joined my group as a JRF funded by a DST-SERB project in March 2023. She joined the PhD program in August 2023. Aahiri is currently working on developing the loop-string-hadron framework for SU(3) gauge theory in higher dimension. She is also performing numerical study of higher dimensional SU(2) theory.
Fran completed his M.Sc. from the University of Zagreb, Croatia in 2023 and joined our group in December 2023. Fran is funded as a JRF in a cross-disciplinary research project of BITS-Pilani being investigated by Prof. Himadri Mukherjee, Department of Mathematics, and myself. Fran is interested in developing quantum algorithms for simulating gauge theories.

Grad Student
Nisa is interested in studying strongly correlated condensed matter physics models and quantum materials and her research is primarily supervised by Prof. Rudranil Basu and is co-supervised by IR. Nisa is exploring quantum information theoretic toolbox for her research goal and also interested in quantum simulation as a probe to explore properties of quantum materials.
