photon gas

[′fō‚tän ‚gas]
(statistical mechanics)
An electromagnetic field treated as a collection of photons; it behaves as any other collection of bosons, except that the particles are emitted or absorbed without restriction on their number.

For example, in [3, 28], Maxwell-Boltzmann distribution functions are used to calculate the thermodynamics of photon gas. Reference  is based on model 1.
We must note that Camacho and Macias  have already visited the thermodynamics of photon gas within this model.
Thermodynamics of Photon Gas with Deformed Dispersion Relation in Model 1
The frequency distribution of the zero point energy is then reconsidered in Section 5, the cosmic equilibrium of a zero point energy photon gas is elaborated in Section 6, and the acceleration of the expansion is estimated in Section 7.
6 Equilibrium of a photon gas in its gravitational field
In a gas cloud of photons of zero point energy, there is an antigravity force due to the photon gas pressure gradient, and a gravitation force due to the intrinsic mass of the same photons as determined by the total energy according to Einstein's mass-energy relation.
Thermodynamics of photon gas has been investigated explicitly within the Magueijo-Smolin Lorentz invariant DSR model .
Photon Gas Thermodynamics in Noncommutative Spacetime
The only difference is that we are going to employ Bose-Einstein distribution function to solve the partition function for photon gas. As photons are spin-one massless quantum particles, it is mandatory to use Bose-Einstein distribution.
When subjecting local energy conservation in a Friedmann-Lemaitre-Robertson-Walker (FLRW) universe to this equation of state the numerical temperature (T)-redshift (z) relation (T(z)) of the CMB follows; see Figure 1 [27, 28], where a comparison with the conventional U(1) photon gas is shown.
We consider two cases: ideal gas and photon gas. It is worth mentioning that a different version of GUP has been studied with ideal gas in [46, 47].
Using the partition functions, we determine all thermodynamical properties of the photon gas. Entropy and internal energy density, respectively, are as follows:
