Thermodynamic horizons in f(Q) gravity: Revealing cosmic dynamics
In this study, we investigate the cosmic dynamics admitting thermodynamic analysis in theory, where 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 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.
期刊介绍:
Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
