The postulates of gravitational thermodynamics.

An inherent structure view of liquid-vapor interfaces.

The formal statistical mechanical theory describing liquid-vapor interfaces at thermal equilibrium has been incomplete, owing partly to discrepancies between two primary views, the local free energy approach originated by van der Waals and the capillary wave approach initiated by Mandelstam. The former provides detailed prescriptions for interfacial density profiles and surface tensions, and ha...

The braneworld stability and large-scale correction in graphene like background

In this work, we consider a graphene-like background in braneworld scenario which is one of the interesting models in cosmology and theoretical physics. Indeed, this paper is an application of holography in condense matter. We use the geometric form of potential which help to obtain field equations and solve it to obtain the energy spectrum. In that case we calculate superpotential and energy d...

Toward the New Gravitational Noncommutative Mechanics and Statistical Mechanics of Quantum Black Holes

This is a short account of our work on the statistical mechanics of ‘cold’ quantum black holes in the constituent model of a black hole 3 4 . A quantum Schwarzschild black hole consists of gravitational atoms of Planckian mass scale 3 4 . The gapless bosonic collective excitations of a bound state of N gravitational atoms dominate the thermodynamics of a cold quantum black hole. It turns out th...

Classical thermodynamics of gravitational collapse

Study of Solar Magnetic and Gravitational Energies Through the Virial Theorem

Virial theorem is important for understanding stellar structures. It produces an interesting connection between magnetic and gravitational energies. Using the general form of the virial theorem including the magnetic field (toroidal magnetic field), we may explain the solar dynamo model in relation to variations of the magnetic and gravitational energies. We emphasize the role of the gravitatio...
