Negative specific heat with trapped ultracold quantum gases
The second law of thermodynamics normally prescribes that heat tends to disperse, but in certain cases it instead implies that heat will spontaneously concentrate. The spontaneous formation of stars…
Statistical Mechanics of planar stellar systems: Solving divergences in self-gravitational systems
Cosmographic Thermodynamics of Dark Energy
TLDR
It is suggested that the cosmological constant may be viewed as an effective approach to dark energy either at small or high redshift domains.

The scattering and thermodynamic properties of ultracold 20Ne vapor
A New Thermodynamics from Nuclei to Stars
TLDR
It is shown that the second law is a natural consequence of the statistical nature of thermodynamics which describes all systems with the same -- redundant -- set of few control parameters simultaneously and even works in systems which are by far than any thermodynamic "limit".
Thermodynamics and Self-Gravitating Systems
This work assembles some basic theoretical elements on thermal equilibrium, stability conditions, and fluctuation theory in self-gravitating systems illustrated with a few examples. Thermodynamics…

Conditions for negative specific heat in systems of attracting classical particles
Thermodynamics of rotating self-gravitating systems
Abstract:We investigate the statistical equilibrium properties of a system of classical particles interacting via Newtonian gravity, enclosed in a three-dimensional spherical volume. Within a…

Thermodynamics of a black hole in a cavity
We present a unified thermodynamic description of configurations consisting of self-gravitating radiation with or without a black hole. We compute the thermal fluctuations and evaluate where they…

Generalized second law of thermodynamics in black-hole physics
In previous work we introduced the concept of black-hole entropy, which we identified with the surface area of the black hole in question expressed in units of the Planck length squared. We suggested…
On the equilibrium statistical mechanics of isothermal classical self-gravitating matter
The canonical ensemble is investigated for classical self-gravitating matter in a finite containerΛ[d]⊂ℝd,d=3 and 2. Starting with modified gravitational interactions (smoothed-out singularity), it…
Dynamics of a pair of spherical gravitating shells.
TLDR
This work considers a different one-dimensional gravitating system consisting of nonrotating concentric mass shells and finds that the ergodic properties of this system are more robust than its planar counterpart.
Black hole explosions?
QUANTUM gravitational effects are usually ignored in calculations of the formation and evolution of black holes. The justification for this is that the radius of curvature of space-time outside the…

Evidence for a black hole from high rotation velocities in a sub-parsec region of NGC4258

Systems with negative specific heat
Some systems for which the binding energy increases more rapidly than linearly with the number of particles, are shown to exhibit negative specific heatc for some energies. In thermal contact with…
