Physical observers, T-vacuum and Unruh like effect in the radiation dominated early universe
Abstract We report the existence of an Unruh like effect, for physical observers (cosmo- logical and comoving observers) in the radiation dominated early universe, which is possible due to the discovery of a new vacuum state (referred here as the T−vacuum). Both the comoving and the cosmological obs...
