论文摘要
我们研究了在开放边界条件下非热系统系统的时间演化过程，并在分析的非热式系统中证实了动态皮肤效应，并揭示了其形成的机理，这是由非铁皮皮肤效应和Hermitian波浪散布引起的。此外，我们发现，与遗传学情况下的均匀速度运动相反，高斯波包可以在非铁族系统中的时间演化过程中加速和放大。发现这种额外的运动是导致动态皮肤效应的原因。
We study the time evolution processes of non-Hermitian systems under the open boundary condition and confirm that the dynamical skin effect exists in non-Hermitian systems analytically, and unveil the mechanism of its formation, which is caused by both the non-Hermitian skin effect and the Hermitian wave packet spreading. Furthermore, we find that in contrast to the uniform speed motion in Hermitian situations, the Gaussian wave packet can be accelerated and amplified during its time evolution in non-Hermitian systems. This additional motion is found to be responsible for the dynamic skin effect.
