Negative specific heat with trapped ultracold quantum gases

- Physics
- 2014

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…

Cosmographic Thermodynamics of Dark Energy

It is suggested that the cosmological constant may be viewed as an effective approach to dark energy either at small or high redshift domains.

A New Thermodynamics from Nuclei to Stars

- PhysicsEntropy
- 2004

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

- Physics
- 2002

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…

Thermodynamics of a black hole in a cavity

- Physics
- 1995

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

- Physics
- 1974

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

- Physics
- 1989

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.

- PhysicsChaos
- 1997

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?

- PhysicsNature
- 1974

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…

An Introduction to the Study of Stellar Structure

- PhysicsNature
- 1939

EDDINGTON'S “Internal Constitution of the Stars” was published in 1926 and gives what now ranks as a classical account of his own researches and of the general state of the theory at that time. Since…

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

- Physics, GeologyNature

MANY galaxies are thought to contain massive black holes— exceeding ten million solar masses—at their centres1,2, but firm observational evidence has proved to be surprisingly elusive. The best…

Systems with negative specific heat

- Physics
- 1970

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…

Internal dynamics of globular clusters
