Welcome to my Homepage

Hello! I am Dipankar Barman, a research scholar and PMRF fellow at the Department of Physics, IIT Guwahati. I received my M.Sc. degree in Physics from IIT Madras in 2020. Then, I joined IIT Guwahati as a Ph.D. scholar under the supervision of Dr. Bibhas Ranjan Majhi. My thesis work is entitled Influence of Gravity on Quantum Entanglement. I was awarded the prestigious Prime Minister's Research Fellowship (PMRF) in the May 2021 (lateral entry) cycle.

My PhD Research Work

Influence of Gravity on Quantum Entanglement

Quantum nature of gravity is yet to be understood. Quantum entanglement phenomenon (QEP) is expected to play a significant role in illuminating this. Therefore it is natural to understand the role of gravity on QEP. Here we target this through the following investigations.
(a) How entanglement properties between two accelerated frames behave when they interact with background quantum fields (non-thermal and thermal)?
(b) What is the influence of curvature of spacetime on QEP?
(c) Nature of QEP in different stages of (FLRW) Universe.
(d) What is the role of excited fields states on QEP?
