简介：现在的工作被奉献给在冻结的magnetar赋予以对一个电场直角的一个极端强壮的磁场的外壳中演变的波色子的学习，两个都由周期的功能描述了。我们沿着盎士通过一个维的潜在的障碍讨论量通道过程。KleinGordon方程的答案以Mathieu为可计算出来的粒子的精力范围，正在转弯从的功能被表示对指数地沿着盎士种模式摆动。在JeffreysWentzelKramersBrillouin框架以内，传播系数在不稳定性范围的中间为粒子动量被计算。

简介：Sub-10-nm体积n-MOSFET(金属氧化物半导体地效果晶体管)直接source-to-排水管通道水流密度使用Wentzel-Krammers-Brillouin(WKB)传播通道理论被模仿了。隧道长度和障碍高度上的source-to-drain通道水流的依赖被检验。倒置层量子化，变窄的乐队差距，和导致的障碍降低完成的排水管在模型被包括了。漏水流密度在4nm隧道长度下面严重地增加，这被观察了，因此把限制放到按比例缩小MOSFET。结果与已经在文学报导的数字结果仔细匹配。
