光力学领域为我们提供了几个量子光子-声子界面的例子。在这篇论文中，我们从理论上研究了微加工光机械阵列中量子关联的产生和操纵。我们考虑一个系统，包括本地化的光子和声子模式相互作用，通过辐射压力在每个晶格位置与相邻站点之间的光子和声子的跳跃的可能性。我们表明，这样的相互作用可以关联的驱动耦合光机阵列的各种模式与精心选择的系统参数。此外，在高斯涨落的线性化区域中，量子关联不仅在存在热噪声的情况下存活，而且还可以通过热产生。我们发现，这些光机阵列提供了一个合适的平台，各种多体系统的量子模拟。
The field of optomechanics provides us with several examples of quantum photon-phonon interface. In this paper, we theoretically investigate the generation and manipulation of quantum correlations in a microfabricated optomechanical array. We consider a system consisting of localized photonic and phononic modes interacting locally via radiation pressure at each lattice site with the possibility of hopping of photons and phonons between neighboring sites. We show that such an interaction can correlate various modes of a driven coupled optomechanical array with well-chosen system parameters. Moreover, in the linearized regime of Gaussian fluctuations, the quantum correlations not only survive in the presence of thermal noise, but may also be generated thermally. We find that these optomechanical arrays provide a suitable platform for quantum simulation of various many-body systems.
