Bibhas Ranjan Majhi is a member of the following research group and research areas:

Research areas

  • General theory of relativity, Field theory on curved spacetimes, Black holes, Cosmology, Thermodynamical aspects of gravity, Fluid-gravity correspondence.

My interest lies on different aspects of General theory of Relativity and Cosmology, both at the classical and quantum levels. I worry a lot about putting together the principles of quantum theory and gravity in a consistent manner. The ultimate goal is to understand the ``ATOMS'' which constitute our spacetime. I am mainly working on general theory of relativity, quantum field theory on curved spacetime, cosmology - more precisely Hawking radiation, Unruh effect, thermodynamics of gravity, quantum (gravitational) anomalies, fluid-gravity correspondence, phenomenology in presence of horizon, etc.
