Gravity and Quantum Theory: Domains of Conflict and Contact
T. Padmanabhan
There are two strong clues about the quantum structure of spacetime and the gravitational dynamics, which are almost universally ignored in the conventional approaches to quantize…
Boundary Term in the Gravitational Action is the Heat Content of the Null surfaces
Sumanta Chakraborty, T. Padmanabhan
The Einstein-Hilbert Lagrangian has no well-defined variational derivative with respect to the metric. This issue has to be tackled by adding a suitable surface term to the action,…
Obtaining the Non-relativistic Quantum Mechanics from Quantum Field Theory: Issues, Folklores and Facts
T. Padmanabhan
Given the classical dynamics of a non-relativistic particle in terms of a Hamiltonian or an action, it is relatively straightforward to obtain the non-relativistic quantum mechanic…
General Relativity from a Thermodynamic Perspective
T. Padmanabhan
I show that the gravitational dynamics in a bulk region of space can be connected to a thermodynamic description in the boundary of that region, thereby providing clear physical in…
Thermodynamical Aspects of Gravity: New insights
T. Padmanabhan
The fact that one can associate thermodynamic properties with horizons brings together principles of quantum theory, gravitation and thermodynamics and possibly offers a window to…
