Particle production and complex path analysis

- K. Srinivasan, T. Padmanabhan
- Physics
- 8 December 1998

This paper discusses particle production in Schwarzschild-like spacetimes and in a uniform electric field. Both problems are approached using the method of complex path analysis which is used to… Expand

Thermodynamical aspects of gravity: new insights

- T. Padmanabhan
- Geology
- 25 March 2010

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 the nature of… Expand

Antonov Instability and Gravothermal Catastrophe---Revisited

- T. Padmanabhan
- Physics
- 1 November 1989

A straightforward and simplified derivation of the Antonov instability and gravothermal catastrophe is obtained by explicitly solving the zero eigenvalue equation associated with the second variation… Expand

Equipartition of energy in the horizon degrees of freedom and the emergence of gravity

- T. Padmanabhan
- Physics
- 16 December 2009

It is possible to provide a physical interpretation for the field equations of gravity based on a thermodynamical perspective. The virtual degrees of freedom associated with the horizons, as… Expand

From gravitons to gravity: myths and reality

- T. Padmanabhan
- Physics
- 1 March 2008

There is a general belief, reinforced by statements in standard textbooks, that: (i) one can obtain the full nonlinear Einstein theory of gravity by coupling a massless, spin 2 field hab… Expand
