Modification of the Complex Scalar Field Lagrangian in FLRW Space-Time and Its Cosmological Outcomes.

Authors: Subhayan Maity, Parna Patra

The most popular approach of understanding the cosmic evolution is Einstein’s General Relativity(GR). GR is the classical gateway to obtain the dynamics of the cosmic fluid and it canat best describe the macroscopic evolution of the Universe. In this work, we have accomplishedan alternative tool to examine the microscopic dynamics of the cosmic fluid particles via quantumfield theory (QFT). We have proposed a cosmic fluid model with complex scalar field Lagrangiancorresponding to the modified Klein-Gordon equation (KG equation) of the scalar field in FLRWspace-time. Following this Lagrangian, the cosmic fluid system has been quantized under certainrestrictions on the parameters. This restrictions are used to determine the cosmic evolution patternin the macroscopic level.
