动态调谐零间隙周期系统的时间反转
Time-reversal in dynamically-tuned zero-gap periodic systems
摘要：
我们发现，在零间隙周期系统中传播的短脉冲可以通过使用弱非绝热调谐的波速在时间尺度上，可以比周期慢得多，以100%的效率被逆转。与以前的计划，我们证明了反转{ \em宽带}（几个周期）脉冲与简单的结构。因此，我们的方案可能为以前无法实现的各种系统的时间反演开辟道路。
英文摘要：
We show that short pulses propagating in zero-gap periodic systems can be reversed with 100% efficiency by using weak non-adiabatic tuning of the wave velocity at time-scales that can be much slower than the period. Unlike previous schemes, we demonstrate reversal of {\em broadband} (few cycle) pulses with simple structures. Our scheme may thus open the way to time-reversal in a variety of systems for which it was not accessible before.
