Quantum driven Bounce of the future Universe
S.K.Srivastava

TL;DR
This paper shows that quantum effects cause the universe's expansion to halt, reverse, and then bounce back into a new, non-singular expanding phase, suggesting a cyclic cosmological model driven by quantum back-reaction.
Contribution
It introduces a quantum-driven mechanism for a universe bounce, demonstrating how quantum back-reaction can lead to a cyclic cosmology without singularities.
Findings
Universe expansion halts and reverses due to quantum back-reaction.
The universe contracts to a small size and then bounces back.
A non-singular, exponentially expanding universe is re-established after the bounce.
Abstract
It is demonstrated that due to back-reaction of quantum effects, expansion of the universe stops at its maximum and takes a turnaround. Later on, it contracts to a very small size in finite future time. This phenomenon is followed by a " bounce" with re-birth of an exponentially expanding non-singular universe.
