“…Large-scale predictions of axion models are the same as in CDM, but small-scale predictions seem to be more in accordance with observations [31]. The BEC of axions has not only proven to be a viable dark matter candidate [31,33], but it also provides plausible explanations for dark energy and its relation with dark matter [32,33].…”

“…Besides dark matter stars, Bose-Einstein condensates are popular in cosmology as an alternative to the standard CDM model in small scales (∼ 10 kpc or less) [31]. Such models are based on the supposition that dark matter is composed of very light hypothetical bosons (m ∼ 10 −21 − 10 −22 eV), known as axions [31][32][33][34][35]. Large-scale predictions of axion models are the same as in CDM, but small-scale predictions seem to be more in accordance with observations [31].…”

We study the thermodynamic properties of a relativistic magnetized neutral vector boson gas at any temperature. By comparing the results with the low temperature and the non relativistic descriptions of this gas, we found that the fully relativistic case can be separated in two regimes according to temperature. For low temperatures, magnetic field effects dominate and the system shows a spontaneous magnetization, its pressure splits in two components and, eventually, a transversal magnetic collapse might occur. In the high temperature region, the gas behavior is led by pair production. The presence of antiparticles preserves the isotropy in the pressure, and increases the magnetization and the total pressure of the system by several orders.

“…In work [23], it was shown how the structure of particles and the inter-action between them can be efficiently taken into account by means of μ-and 𝑞-deformed bosons. The authors of works [24,25] considered 𝜇-and 𝑞-deformed bosons as dark matter models.…”

Two approaches to the construction of thermodynamics in the framework of the q- and м-formalisms, which correspond to certain deformations of the algebra of the creation–annihilation operators, have been considered. By comparing the obtained results, an approximate, independent of the space dimension, correspondence was revealed between the second virial coefficients for the ideal q- and м-deformed Bose gases. The corresponding discrepancy arises only at the level of the third virial coefficient. A method for emulating the м-deformed Bose gas up to the third virial coefficient inclusive by means of the two-parametric nonadditive Polychronakos statistics is demonstrated.
