一维光机阵列的失超动力学

Quench Dynamics in 1D Optomechanical Arrays

Sadegh Raeisi, Florian Marquardt

摘要:

由外部参数的快速变化引起的非平衡动力学与许多物理学领域的广泛场景有关。对于空间周期系统中的波,猝灭将改变能带结构并产生新的激发。在拓扑能带结构的情况下,当通过拓扑相变淬火时,边界处的缺陷模式可以被产生或破坏。在这里,我们表明,光学机械阵列是一个很有前途的平台,研究这种动力学,因为它们的能带结构可以通过控制激光时间调谐。我们研究了在一维阵列中非平衡光学和机械激发的产生,包括苏-施里弗-希格模型的玻色子版本。这些思想可以推广到其他系统,如驱动非线性腔阵列。

英文摘要:

Non-equilibrium dynamics induced by rapid changes of external parameters is relevant for a wide range of scenarios across many domains of physics. For waves in spatially periodic systems, quenches will alter the bandstructure and generate new excitations. In the case of topological bandstructures, defect modes at boundaries can be generated or destroyed when quenching through a topological phase transition. Here, we demonstrate that optomechanical arrays are a promising platform for studying such dynamics, as their bandstructure can be tuned temporally by a control laser. We study the creation of nonequilibrium optical and mechanical excitations in 1D arrays, including a bosonic version of the Su-Schrieffer-Heeger model. These ideas can be transferred to other systems such as driven nonlinear cavity arrays.
