Abstract:In optomechanical systems, the libration and rotation of nanoparticles provide profound insights for ultrasensitive torque measurements and macroscopic quantum superpositions. The achievements include transitioning the libration to the rotation up to 6 GHz and cooling the libration to millikelvin temperatures. Libration and rotation are driven by restoring and constant optical torques, respectively. However, the transition mechanisms between these two states warrant further exploration. From this perspective, … Show more
