“…Based exclusively on the modified dispersion relations (MDRs), the investigation of many facets of a given theory may be undertaken [31], including its thermal behavior. In the literature, there exists a variety of recent works involving the thermodynamic properties in many different contexts, namely, Lorentz violation [32][33][34][35][36][37][38][39][40][41][42], bouncing Universe [43], loop quantum gravity [44], Einstein-aether theory [45], graviton [46], five-dimensional Chern-Simons theory [47] and others [48][49][50][51]. Nevertheless, from a MDR, there does not exist up to now a thermal study of massive particles in the Ellis wormhole scenario.…”

In this work, we analyze the thermodynamic properties of non--interacting particles under influence of the gravitational field of a traversable wormhole. In particular, we investigate how the thermodynamic quantities are affected by the Ellis wormhole geometry, considering three different regions to our study: asymptotically far, close to the throat, and at the throat. The thermodynamic quantities turn out to depend strongly on parameter that controls the wormhole throat radius. By varying it, there exist an expressive modification in the thermodynamic state quantities, exhibiting both usual matter and dark energy--like behaviors. Finally, the interactions are regarded to the energy density and it seem to indicate that it ``cures" the dark energy--like features.

“…It was shown in [16,17] how the CPT-even and CPT-odd Lorentz violating terms modify the BEC critical temperature and the thermodynamic parameters. In [19] the influence of the anisotropic scaling in the BEC was discussed. The possi-bility of probing low-energy Lorentz violating effects in dipolar BEC was addressed in [18].…”

In this paper, we study the effects of rainbow gravity on relativistic Bose-Einstein condensation and thermodynamics parameters. We initially discussed some formal aspects of the model to only then compute the corrections to the Bose-Einstein condensation. The calculations were carried out by computing the generating functional, from which we extract the thermodynamics parameters. The corrected critical temperature T c that sets the Bose-Einstein Condensation was also computed for the three mostly adopted cases for the rainbow functions. We have also obtained a phenomenological upper bound for a combination of the quantities involved in the model, besides showing the possibility of occurrence of the Bose-Einstein condensation in two spatial dimensions under appropriate conditions on those functions. Finally, we have discussed how harder is for the particles at an arbitrary temperature T < T c to enter the condensed state when compared with the usual scenario.

In this paper, we study the effects of a modified theory of gravity - the rainbow gravity - on the relativistic Bose-Einstein condensate (BEC). We initially discuss some formal aspects of the model in order to compute the corrections to the relevant quantities of the condensate. Following, we evaluate the generating functional from which obtain some thermodynamic parameters. Then we calculate the corrected critical temperature $T_c$ that sets the relativistic Bose-Einstein condensate considering the three principal rainbow functions, finding, in addition, a phenomenological upper bound for the parameters involved in the model. Finally, we discuss how harder is for the particles at an arbitrary temperature $T<T_c$ to enter the condensed state upon comparing with the usual scenario, {\it i.e.}, without rainbow gravity.
