To elucidate the noncentrosymmetric nature of the Rashba superconductor, we have investigated the nonreciprocal transport in gated SrTiO3, which is known as a 2D Rashba superconductor. We found the gigantic enhancement in the nonlinear resistance in the amplitude and phase fluctuation regions. Also, we discuss the possible origins of nonreciprocity in the 2D Rashba superconductor, such as paraconductivity with a parity mixing in the Cooper pairs and rectified vortex-antivortex motions.
