Коллективное влияние примесей на динамику кинков уравнения синус-Гордона
Компьютерные исследования и моделирование, 2013, т. 5, № 3, с. 403-412

С помощью численных методов исследована динамика кинков модифицированного уравнения синус-Гордона в модели с локализованной пространственной модуляцией периодического потенциала (или примесью). Рассмотрен случай наличия двух одинаковых примесей. Показано, что возможно наблюдение коллективных эффектов влияния примесей, которые сильно зависят от расстояния между ними. Продемонстрировано наличие определенного критического значения расстояния между примесями, которое приводит к двум качественно различным сценариям динамического поведения кинка.

Ключевые слова: кинк, бризер, уравнение синус-Гордона, квазитуннелирование.

Collective influence of impurities on the dynamics of kinks of modified sine-Gordon equation
Computer Research and Modeling, 2013, v. 5, no. 3, pp. 403-412

We investigated numerically the dynamics of kinks of modified sine-Gordon equation in the model with localized spatial modulation of a periodic potential (or impurity). We considered the case of two identical impurities. We showed the possibility of collective effects of the influence of impurities, which are heavily dependent on the distance between them. We demonstrated the existence of a certain critical value of the distance between impurities, which has two qualitatively different scenarios of the dynamic behavior of kink.

Keywords: kink, breather, sine-Gordon equation, quasitunneling.
