AI 中文摘要
我们运用微扰理论研究非线性克莱因 - 戈登($\phi^4$和正弦 - 戈登)链以及离散串联约瑟夫森传输线中的扭结。展开参数是晶格周期与扭结宽度之比。次领先阶近似修正了先前领先阶近似得到的扭结轮廓。
英文摘要
We use perturbation theory to study kinks in nonlinear Klein--Gordon ($ϕ^4$ and sine-Gordon) chains and in a discrete series-connected Josephson transmission line. The expansion parameter is the ratio of the lattice period to the kink width. The next-to-leading-order approximation modifies the kink profiles obtained previously in the leading-order approximation.
