Thermodynamic horizons in f(Q) gravity: Revealing cosmic dynamics
In this study, we investigate the cosmic dynamics admitting thermodynamic analysis in f(Q) theory, where Q describes the non-metricity. We employ a reconstruction technique with an appropriate scale factor to assess how this modified framework influences cosmic evolution. Moreover, we examine the gr...

| description | In this study, we investigate the cosmic dynamics admitting thermodynamic analysis in f(Q) theory, where Q describes the non-metricity. We employ a reconstruction technique with an appropriate scale factor to assess how this modified framework influences cosmic evolution. Moreover, we examine the graphical representation of relevant cosmological quantities to investigate the contraction and expansion phases of the universe surrounding the bounce transition. Further, we investigate the second law of thermodynamics in the context of the bouncing framework. Our results indicate the violation of null energy condition which ensure the existence of viable cosmological bounce solutions in f(Q) theory. The equation of state parameter reveals that the universe experiences cosmic accelerated acceleration. It is found that this gravitational theory effectively presents viable alternatives to the standard cosmological scenarios, hence providing valuable understanding of the gravitational force and the early universe. |
