Is the emergent scenario in the early Universe a consequence of the quantization of the real scalar field?Author(s): Subhayan Maity* and Sujayita Bakra
The emergent scenario of cosmic evolution is a topic of great interest in recent cosmology, especially because it describes a non-singular origin of the Universe unlike the Big-Bang models. This types of cosmic evolution pattern have already been established through the nonequilibrium thermodynamic prescription. But those models are phenomenological and require physical interpretation from the quantum field theory perspective. This work is an effort to search a quantum field theoretical reason to justify the emergent nature of the Universe and the nature of cosmic evolution at the early phase of the cosmic expansion.
