A minimal and stable vacuum bounce in exponential f(R) gravity
Abstract We investigate the realization of a nonsingular cosmological bounce in metric f(R) gravity using a controlled exponential deformation of the Starobinsky $$R^{2}$$ R 2 model. Adopting a smooth Gaussian-type bouncing scale factor, we first demonstrate a no-go result showing that a positive-cu...
