Statistical mechanics of gravitating systems
Cosmological constant—the weight of the vacuum
Particle production and complex path analysis
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…
Cosmology and astrophysics through problems

Thermodynamical aspects of gravity: new insights
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…
Antonov Instability and Gravothermal Catastrophe---Revisited
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…
Equipartition of energy in the horizon degrees of freedom and the emergence of gravity
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…
From gravitons to gravity: myths and reality
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…
