Abstract Non-Hermitian systems with anti-parity-time (aPT) symmetry have revealed rich physics beyond conventional systems. Here, we study optomechanics in an aPT-symmetric spinning resonator and show that, by tuning the rotating speed to approach the exceptional point (EP) or the non-Hermitian spectral degeneracy, nonreciprocal light transmission with a high isolation ratio can be realized.
