摘要:

研究了PT对称非线性晶格中局域模的存在性。所考虑的系统揭示了不寻常的性质:不同于其他典型的耗散系统,它具有家庭(分支)的解决方案,这可以通过传播常数参数化;相对狭窄的本地化模式似乎是稳定的,即使当保守的非线性晶格势是缺席的;最后,系统支持稳定的多极解。

英文摘要:

Existence of localized modes supported by the PT-symmetric nonlinear lattices is reported. The system considered reveals unusual properties: unlike other typical dissipative systems it possesses families (branches) of solutions, which can be parametrized by the propagation constant; relatively narrow localized modes appear to be stable, even when the conservative nonlinear lattice potential is absent; finally, the system supports stable multipole solutions.
