Quantum many-body dynamics in optomechanical arrays

Understand

We study the nonlinear driven dissipative quantum dynamics of an array of optomechanical systems.

• At each site of such an array, a localized mechanical mode interacts with a laser-driven cavity mode via radiation pressure, and both photons and phonons can hop between neighboring sites.
• The competition between coherent interaction and dissipation gives rise to a rich phase diagram characterizing the optical and mechanical many-body states.
• For weak intercellular coupling, the mechanical motion at different sites is incoherent due to the influence of quantum noise.
