Physical non-equivalence of the Jordan and Einstein frames (1003.5394v2)
Published 28 Mar 2010 in gr-qc, astro-ph.CO, and hep-th
Abstract: We show, considering a specific f(R)-gravity model, that the Jordan frame and the Einstein frame are physically non-equivalent, although they are connected by a conformal transformation which yields a mathematical equivalence. Since all the calculations are performed analytically, this non-equivalence is shown in an unambiguous way.
