Electron in a system of two plane quantum waveguides coupled through small window is considered. The method of matching the asymptotic expansions of the boundary problem solution is used. The dependence of entropy on the window width is described. for the case of small window in the framework of the asymptotic approach.

Рассматривается электрон в системе из двух плоских квантовых волноводов, связанных через малое окно. Используется метод согласования асимптотических разложений решения краевой задачи. Описывается зависимость энтропии от ширины окна для случая малого окна в рамках асимптотического подхода.
