Abstract
In this Letter, we propose a scheme to achieve a nonreciprocal conventional photon blockade in a nonlinear device consisting of an atom and spinning cavity by manipulating the detuning between the atom and the cavity. We show that the single-photon blockade can be generated by driving the spinning resonator from one side, while photon-induced tunneling is driven by the other side with the same driving strength. This nonreciprocal conventional photon blockade effect originates from the Fizeau-Sagnac drag, which leads to different splitting of the resonance frequencies for the counter-circulating modes. We give four optimal solutions for Fizeau-Sagnac shifts to generate a nonreciprocal conventional photon blockade with the arbitrary detunings between atom and cavity.
