论文摘要
我们提出了一个非线性多模超导电声系统，其中超导能力电感和压电强耦合之间的相互作用在10 GHz的多个声学模式之间建立了有效的Kerr非线性，这几乎可以通过固有的机械性非线性来实现。通过激发单个微波音调的多模kerr系统，我们进一步演示了一个连贯的电声频率梳子，并在SuperStrong耦合极限中对多模型非线性相互作用提供了理论上的理解。这种非线性超导电声系统阐明了多模谐振系统的主动控制，并为微波频率下的微型群岛动态研究提供了一个有利的平台。
We present a nonlinear multimode superconducting electroacoustic system, where the interplay between superconducting kinetic inductance and piezoelectric strong coupling establishes an effective Kerr nonlinearity among multiple acoustic modes at 10 GHz that could hardly be achieved via intrinsic mechanical nonlinearity. By exciting this multimode Kerr system with a single microwave tone, we further demonstrate a coherent electroacoustic frequency comb and provide theoretical understanding of multimode nonlinear interaction in the superstrong coupling limit. This nonlinear superconducting electroacoustic system sheds light on the active control of multimode resonator systems and offers an enabling platform for the dynamic study of microcombs at microwave frequencies.
