摘要

周期性极端波，其特点是其反复出现和异常高的振幅，在各个科学学科中得到了极大的关注。在本研究中，我们考虑具有位置相关非线性相互作用强度的非互反DNLS方程。我们证明了时间周期极端波可以出现在非厄米晶格中。当考虑非厄米系统中适当的位置相关非线性相互作用强度时，我们还证明了长寿命的离散极端波是可能的。

Time Periodic Extreme Waves in a Non-Hermitian Lattice

Periodic extreme waves, characterized by their recurrent and exceptionally high amplitudes, have gained significant attention in various scientific disciplines. In this study, we consider a nonreciprocal DNLS equation with position-dependent nonlinear interaction strength. We show that time-periodic extreme waves can occur in a non-Hermitian lattice. We also demonstrate that long-living discrete extreme waves is possible when considering proper position-dependent nonlinear interaction strength in a non-Hermitian system.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
