New agegraphic dark energy in loop quantum cosmology: a quantum gravitational perspective on dark energy evolution

Abstract In this work, we explore the new agegraphic dark energy model within the framework of Loop Quantum Cosmology (LQC). A quantum gravitational perspective on the dark energy evolution is explored. A combination of cold dark matter and dark energy in the form of New Agegraphic dark energy is considered with LQC as the background gravity theory. Both the interacting and non-interacting scenarios between dark energy and matter are considered. Various cosmological parameters, like the equation of state parameter, deceleration parameter, and statefinder parameters, are studied. The squared speed of sound is investigated to get an idea about the stability of the system. An observational data analysis using recent cosmological data and the Markov chain Monte Carlo algorithm is performed to constrain the free parameter space of the model. Our findings imply that the interaction of loop quantum effects with agegraphic dark energy offers a nonsingular origin scenario and a theoretically sound and observationally compatible explanation of the universe’s late-time acceleration.
