论文摘要
我们提出了位于非线性光子时间晶体的动量间隙（k-gap）中的超亮孤子。这些间隙孤子构成在空间中的平面波，同时定期自行重建波袋。孤子来自具有无限基团速度的模式，导致超亮性进化，这与位于零组速度的能隙（或空间间隙）边缘的类似Bragg Gap孤子的固定性相反。鉴于爱因斯坦的因果关系，我们通过引入截断的输入种子作为信号速度先驱的前体，发现这些k-gap孤子的传播比光的脉冲传播更快，并发现K-GAP唯一子的乳腺静脉曲张的传播是K-GAP唯一的乳头泌尿剂不会破坏因果关系。
We propose superluminal solitons residing in the momentum gap (k-gap) of nonlinear photonic time-crystals. These gap solitons are structured as plane-waves in space while being periodically self-reconstructing wavepackets in time. The solitons emerge from modes with infinite group velocity causing superluminal evolution, which is opposite to the stationary nature of the analogous Bragg gap soliton residing at the edge of an energy gap (or a spatial gap) with zero group velocity. We explore the faster-than-light pulsed propagation of these k-gap solitons in view of Einstein's causality by introducing a truncated input seed as a precursor of signal velocity forerunner, and find that the superluminal propagation of k-gap solitons does not break causality.
