Description
The inflationary era is mostly related to the classical gravity in the Friedmann–Robertson–Walker (FRW) universe. In this study, we explore the behavior of a nonclassical scalar field in the context of the Friedmann-Robertson-Walker (FRW) universe. We represented the massive inflaton field in the semi-classical gravity using a coherent squeezed vacuum state. This state provides insight into quantum fluctuations, which play a critical role in the early universe, influencing cosmic inflation, structure formation, and the evolution of the universe. Mandel’s Q parameter is useful for examining the nonclassical nature of the inflaton field. Hence, we investigated Mandel’s Q parameter in the cosmological reference with related cosmological parameters for coherent squeezed vacuum state.
