Abstract:
In this thesis, we studied quantumfluctuationandthedarkenergysectorcorrelation
problem in the universe model. Quantum fluctuations, originating from the inherent
uncertainty at the quantum level, and dark energy, hypothesized to drive the uni
verse’s accelerated expansion, represent two fundamental yet enigmatic phenomena
in modern cosmology. Despite significant advancements in understanding each in
dependently, reconciling their relationship remains a profound challenge. Through a
comprehensive review of theoretical frameworks and observational data, this study
was investigated the theoretical basis for quantum fluctuations in the universe, and
its relations to the dynamics of dark energy; inflationary models, quintessence mod
els, and modified gravity theories address the correlation problem between quantum
f
luctuations and dark energy. Moreover we analyzed the observational evidence sup
ports or challenges the correlation between quantum fluctuations and dark energy
in the cosmic microwave background radiation and large-scale structure of the uni
verse and the implications of the correlation between quantum fluctuations and dark
energy for the fundamental nature of dark energy and its role in the evolution of the
universe model.
