Theoretical Gravitational Physics

IIT Gandhinagar

Einstein's theory of general relativity is regarded as one of the highest achievements of human thinking. The theory replaced the Newtonian description of gravity in terms of an action at a distance force with a remarkable spacetime picture. The gravity curves the spacetime, affects the motion of light and the causal structure, leading to exotic objects like black holes. Understanding the quantum and classical physics of black holes is a major research area in theoretical physics.

The recent detection of gravitational waves by LIGO and observing the black hole shadow by the event horizon telescope opened up possibilities to find new gravitational physics beyond Einstein's theory of gravity. Also, holography and AdS-CFT are providing us with radical new pictures about the microscopic structure of spacetime. We live in an exciting time, hopefully on the verge of a new revolution in theoretical physics, similar to the Einsteinian revolution more than 100 years ago. 

Research areas pursued by the theoretical Gravitational Physics group at IIT Gandhinagar are:

General Relativity and Modified Gravity
Black hole Thermodynamics
AdS/CFT and Quantum Information theory
Quantum Field Theory in Curved Spacetime
Application of Quantum Information theory in quantum field theory
