The Nonequilibrium Thermodynamics of Radiation Interaction
نویسندگان
چکیده
We review some important recent developments in the nonequilibrium thermodynamics of radiation and matter-radiation mixtures. These include variational principles for nonequilibrium steady states of photons, neutrinos, and matter in local thermodynamic equilibrium. These variational principles can be extended to include mass and chemical potential. The general nature of radiation entropy, entropy production, equilibrium, and nonequilibrium is also discussed.

Black Hole Evaporation and Nonequilibrium Thermodynamics for a Radiation Field
When a black hole is put in an empty space (zero temperature space) on which there is no matter except the matter of the Hawking radiation (Hawking field), then an outgoing energy flow from the black hole into the empty space exists. By the way, an equilibrium between two arbitrary systems can not allow the existence of an energy (heat) flow from one system to another. Consequently, in the case...
متن کاملMeasuring nonequilibrium temperature of forced oscillators.
The meaning of temperature in nonequilibrium thermodynamics is considered by using a forced harmonic oscillator in a heat bath, where we have two effective temperatures for the position and the momentum, respectively. We propose a concrete model of a thermometer to testify the validity of these different temperatures from the operational point of view. It is found that the measured temperature ...

When a black hole evaporates, there arises a net energy flow from the black hole into its outside environment due to the Hawking radiation and the energy accretion onto black hole. Exactly speaking, any thermal equilibrium state has no energy flow, and therefore the black hole evaporation is a nonequilibrium process. To study details of evaporation process, nonequilibrium effects of the net ene...
