AI总结:

本文在弱耗散非线性电传输线中实验观测 KdV 孤子气体,揭示其由本征模重排和非绝热效应驱动形成相干孤子凝聚体。

摘要:

我们通过实验研究了弱耗散非线性电传输线中 Korteweg-deVries 孤子气体的受扰演化。系统动力学表明,初始稠密且完全随机的孤子气体经非线性谱分析后演化为一种被识别为孤子凝聚体的相干宏观态。该孤子凝聚体的涌现由系统本征模的空间重排,以及非绝热效应导致的新孤子态增殖所驱动;这一现象无法被现有流体动力学理论解释。

英文摘要:

We present an experimental study on the perturbed evolution of Korteweg-deVries soliton gases in a weakly dissipative nonlinear electrical transmission line. The system's dynamics reveal that an initially dense, fully randomized, soliton gas evolves into a coherent macroscopic state identified as a soliton condensate through nonlinear spectral analysis. The emergence of the soliton condensate is driven by the spatial rearrangement of the systems's eigenmodes and by the proliferation of new solitonic states due to nonadiabatic effects, a phenomenon not accounted for by the existing hydrodynamic theories.
