dc.description.abstract	Nonclassical representation of a minimally coupled scalar field in the open and closed FRW universe, is studied in the semiclassical theory of gravity. Particle production of a nonclassical scalar field in the coherent and squeezed state formalisms in the open FRW universe is examined. Numerical solutions to the semiclassical Friedmann equations are obtained for both the closed and open models in the coherent and squeezed state formalisms. Mandel's Q parameter of the quantum optics is studied in the cosmological context with associated cosmological parameters, in the semiclassical theory of gravity. © 2010 World Scientific Publishing Company.
