摘要
我们研究由空间非均匀共形场论描述的大类周期驱动临界系统的普适混沌动力学。通过采用有效曲时空方法，我们显示，量子混沌相关性的发生——即由时序无穷次关联子（OTOC）的Lyapunov指数所捕捉——由新出现的Floquet视界的Hawking温度所决定。Furthermore, scrambling of quantum information is shown to be strongly inhomogeneous, leading to transitions from chaotic to non-chaotic regimes by tuning driving parameters. We finally use our framework to propose a concrete protocol to simulate and measure OTOCs in quantum simulators, by designing an efficient stroboscopic backward time evolution.
