Stimulated adiabatic passage has been extensively studied to achieve robust and selective population transfer in quantum systems. Recently, the quantum-classic analogy has been rapidly developing and can be considered responsible for the implementation of the adiabatic transfer of sound energy in cavity chain systems. In this article, we investigate the adiabatic transfer of sound energy between two topological end states in the Su-Schrieffer-Heeger (SSH) cavity chain, which can be considered to be the acoustic analog of the quantum chirped-pulse excitation. The topological adiabatic passage in SSH cavity chain has two categories. When the single-cavity resonance frequencies on the sublattices A and B in the SSH cavity chain do not switch their spectrum positions, the topologically protected adiabatic evolution results in the returning passage of the sound excited in one end cavity. When a level crossing with single-cavity resonance frequencies on the sublattices A and B exhibits switch in the frequency spectrum, acoustic energy is observed to be topologically pumped between the two end cavities of the SSH chain.

已对刺激绝热通道进行了广泛研究，以实现量子系统中稳定且有选择的种群转移。近来，量子经典比喻已经迅速发展，可以被认为是在空腔链系统中实现声能绝热传递的原因。在本文中，我们研究了Su-Schrieffer-Heeger（SSH）腔链中两个拓扑最终状态之间的声能绝热传递，可以将其视为量子chi脉冲激励的声学模拟。SSH腔链中的绝热通道有两类。当子腔A和B上的单腔共振频率时在SSH腔链中，如果不切换其频谱位置，则受拓扑保护的绝热演化会导致在一端腔中激发的声音返回。当亚晶格A和B上具有单腔共振频率的能级交叉在频谱上表现出切换时，可以观察到声能在拓扑上被泵送到SSH链的两个端腔之间。
