Permanent directional heat currents in lattices of optomechanical resonators

We study the phonon dynamics in lattices of optomechanical resonators where the mutually coupled photonic modes are coherently driven and the mechanical resonators are uncoupled and connected to independent thermal baths. We present a general procedure to obtain the effective Lindblad dynamics of the phononic modes for an arbitrary lattice geometry, where the light modes play the role of an effective reservoir that mediates the phonon nonequilibrium dynamics. We show how to stabilize stationary states exhibiting directional heat currents over arbitrary distance, despite the absence of thermal gradient and of direct coupling between the mechanical resonators.

光机械谐振器晶格中的永久定向热流

我们研究了光机电谐振器的晶格中的声子动力学,其中相互耦合的光子模式被相干地驱动,机械谐振器被解耦并连接到独立的热浴。我们提出了一个通用程序,以获取任意晶格几何结构的声子模式的有效Lindblad动力学,其中光模扮演着有效储层的角色,该储层可以调节声子非平衡动力学。我们展示了如何稳定显示任意方向上的有向热流的稳态,尽管没有热梯度和机械谐振器之间的直接耦合。
