Tolman’s relation for the temperature gradient in an equilibrium self-gravitating general relativistic fluid is broadly accepted within the general relativity community. However, the concept of temperature gradients in thermal equilibrium continues to cause confusion in other branches of physics, since it contradicts naive versions of the laws of classical thermodynamics. In this paper we discuss the crucial role of the universality of free fall. We also provide an interesting pedagogical… 

Gravity’s universality: The physics underlying Tolman temperature gradients

We provide a simple and clear verification of the physical need for temperature gradients in equilibrium states when gravitational fields are present. Our argument will be built in a completely

On the Connections between Thermodynamics and General Relativity

In this thesis, the connections between thermodynamics and general relativity are explored. We review the concept of gravitationally induced temperature gradients in equilibrium states, first

Tolman-like temperature gradients in stationary spacetimes

It is (or should be) well known that specification of a heat bath requires both a temperature and a 4-velocity, the rest frame of the heat bath. In static spacetimes there is a very natural and

Relativistic Gravothermal Instability: the Weight of Heat

Thermal energy points towards a disordered, completely uniform state acting counter to gravity's tendency to generate order and structure through gravitational collapse. It is therefore expected to

Gravitational Instability Caused by the Weight of Heat

The core formed during a core-collapse supernova is subject to the relativistic gravothermal instability, if it becomes sufficiently hot and compactified at the time of the bounce, in this case it will continue to collapse towards the formation of a black hole.

Kinetic formulation of Tolman–Ehrenfest effect: Non-ideal fluids in Schwarzschild and Kerr space-times

A review of the original thermodynamic formulation of the Tolman–Ehrenfest effect prescribing the temperature profile of uncharged fluid at thermal equilibrium forming stationary configurations in

Local temperature in general relativity

We examine the Tolman temperature by using Carter’s variational formalism of thermodynamics. We restrict our interests to fluids in thermal equilibrium that the heat does not propagate. We show that

Inverse magnetorotational catalysis and the phase diagram of a rotating hot and magnetized quark matter

We study the properties of a hot and magnetized quark matter in a rotating cylinder in the presence of a constant magnetic field. To do this, we solve the corresponding Dirac equation using the Ritus

Abstract We discuss two scenarios of emergent gravity. In one of them the quantum vacuum is considered as superplastic crystal, and the effective gravity describes the dynamical elastic deformations

Chiral Phase Transition of a Dense, Magnetized and Rotating Quark Matter

We investigate the chiral symmetry restoration/breaking of a dense, magnetized and rotating quark matter within the Nambu Jona-Lasinio model including N f = 2 and N c = 3 numbers of flavors and

Temperature equilibrium in a static gravitational field

In the case of a gravitating mass of perfect fluid which has come to thermodynamic equilibrium, it has previously been shown that the proper temperature T0 as measured by a local observer would

On the Weight of Heat and Thermal Equilibrium in General Relativity

In accordance with the special theory of relativity all forms of energy, including heat, have inertia and hence in accordance with the equivalence principle also have weight. The purpose of the

The subject for the tenth memorial lecture, the classical principles of thermodynamics were given their most complete and comprehensive expression and the extensions to these classical principles which have since been made necessary by Einstein's discovery of the special and general theories of relativity.
