My research has largely centered on study physics beyond the Standard Model (BSM) and quantum field theory (QFT), where I have successfully developed a novel mechanism for generating particle number asymmetry (PNA) using a two-particle-irreducible and density operator formalism and have formulated the spacetime evolution of lepton family number densities to analyze wave-packet decoherence and distinguish Dirac versus Majorana neutrino mass types. Building upon these established frameworks in non-equilibrium QFT and neutrino phenomenology, my upcoming research proposes to formulate the time and spacetime evolution of cosmic background neutrino lepton numbers and densities within a curved spacetime framework utilizing the FLRW metric. By extending this formulation to handle mixed states via a density matrix approach in the non-relativistic regime and incorporating conformal coupling theory, this proposed work aims to uncover how gravitational modifications alter neutrino oscillation lengths, clarify mass hierarchies, and determine the cosmological implications of background neutrinos as they depart from thermal equilibrium. Recently, I also work on quantum phenomena using the QFT approach.
