field governed universe from NKK theory of gravity : stochastic approach
Inflaton field governed universe from NKK theory of gravity: stochastic approach. Abstract We study a nonperturbative single field (inflaton) governed cosmological model from a 5D Noncompact Kaluza-Klein (NKK) theory of gravity. The inflaton field fluctuations are estimated for different epochs of the evolution of the universe. We conclude that the inflaton field has been sliding down its (quad...

متن کاملDecaying cosmological parameter in the early universe from NKK theory of gravity
Cosmological observations imply that there exists an extremely small upper limit on the vacuum energy density in the present state of our universe. This stands in sharp contradiction with theoretical predictions [1]. In fact, any mass scale in particle physics contributes to the vacuum energy density much larger than this upper bound [2]. According to modern quantum field theory, the structure ...
متن کاملNoncompact KK theory of gravity : stochastic treatment for a nonperturbative inflaton field in a de Sitter expansion
We study a stochastic formalism for a nonperturbative treatment of the infla-ton field in the framework of a noncompact Kaluza-Klein (KK) theory during an inflationary (de Sitter) expansion, without the slow-roll approximation.
