Abstract: Einstein's weak equivalence principle (WEP) states that any freely falling, uncharged test particle follows the same identical trajectory independent of its internal structure and composition. Since the polarization of a photon is considered to be… read more here.

Abstract: The Standard-Model Extension provides a framework to systematically investigate possible violation of the Lorentz symmetry. Concerning gravity, the linearized version was extensively examined. We here cast the first set of experimental bounds on the nonlinear… read more here.

DOI: 10.1103/physrevd.99.103012
Abstract: If the weak equivalence principle (WEP) is broken, the measured values of the parametrized post-Newtonian parameter. from photons with left- and right-handed circular polarizations should differ slightly, leading to the arrival-time difference of these two… read more here.
