Research

My research interest is in the area of non-perturbative aspects of quantum field theories, and in particular Lattice Gauge Theory. My works in lattice Quantum Chromodynamics (QCD) mainly focus on large scale simulations inside femto-worlds to understand the structures and interactions of subatomic particles.

A comprehensive understanding of the structures and interactions of subatomic particles through a first principles study is a challenge in particle physics and lattice gauge theory is the only known way to deal such problems. With advances in peta to exascale computing and better algorithms, Lattice QCD  calculations are providing precise quantitative information on various physical observables in particle and even in nuclear physics.

Highlights of my research are mentioned here. 

Current Interests:

• • • Nuclear physics from lattice QCD

    • Algorithm developments for quantum computing

    • Exotic particles

    • Energy spectra of hadrons, particularly of the charm and bottom hadrons (related to experiments at LHC, Belle and BES)

    • Decay of heavy hadrons (related to CKM, BSM physics)

    • QCD at finite temperature and finite density (phase diagrams, physics of neutron stars) 

    • Three-dimensional image of hadrons through study of spin, angular momenta and PDF (related to experiments at future Electron Ion Collider, USA)
