| Popis: | Photon blockade is an important quantum nonlinear phenomenon in cavity optomechanics. Here, we investigate the two-photon blockade effect by exploiting the mechanical squeezing. This squeezing can enhance the optomechanical-coupling strength into the single-photon strong-coupling regime. With strong coupling, we find the photon blockade effects can be generated and enhanced, and the region where the two-photon blockade occurs can be widened. Finally, we study the transition between photon-induced tunneling and blockade. |
