Optomechanical dynamics in the - and broken--symmetric regimes
arXiv:2107.13891 · doi:10.1103/PhysRevA.104.053518
Abstract
We theoretically study the dynamics of typical optomechanical systems, consisting of a passive optical mode and an active mechanical mode, in the - and broken--symmetric regimes. By fully analytical treatments for the dynamics of the average displacement and particle numbers, we reveal the phase diagram under different conditions and the various regimes of both -symmetry and stability of the system. We find that by appropriately tuning either mechanical gain or optomechanical coupling, both phase transitions of the -symmetry and stability of the system can be flexibly controlled. As a result, the dynamical behaviors of the average displacement, photons, and phonons are radically changed in different regimes. Our study shows that -symmetric optomechanical devices can serve as a powerful tool for the manipulation of mechanical motion, photons, and phonons.
