Уважаемые коллеги!

На заседании Ученого совета в пятницу  10 марта в 11:30 будут заслушаны
2 коротких доклада:

1) _А.М. Дюгаев_, П.Д. Григорьев
*Моделирование двухямных потенциалов для уравнения Шредингера*

Предложен новый метод определения расщепления уровней $\Delta$ в
двухямном одномерном потенциале. Найдены две функции ''партнеры'', одна
симметричная $\Psi_{+}$, другая антисимметричная $\Psi_{-}$. По ним из
уравнения Шредингера найдены отвечающие им потенциалы $V_{+}(x)$ и
$V_{-}(x)$, и энергии $E_{+}^{0}$ и $E_{-}^{1}$. Уникальным свойством
$\Psi_{+}$ и $\Psi_{-}$ является тождественное равенство:
$E_{+}^{0}=E_{-}^{1}$, что дает возможность определить $\Delta$ по
теории возмущений по параметру $V_{+}(x)-V_{-}(x)$. Для двухямного
осцилляторного потенциала показано, что инстантонный предел может быть
получен разложением в ряд теории возмущений по параметру $x_0$: $0

2) _П.Д. Григорьев_, А.М. Дюгаев
*Улучшение ловушек ультрахолодных нейтронов, покрытых пленкой жидкого
гелия, электростатическим потенциалом*

Предлагается использовать электрическое напряжение, приложенное к
шероховатым стенкам ловушки ультрахолодных нейтронов (УХН), покрытых
жидким гелием, для увеличения толщины жидкого гелия и дополнительной
защиты УХН от поглощения в стенках ловушки. Проведенные оценки
необходимой интенсивности электрического поля показывают, что оно
реализуемо. Изучается возможность влияния электрического поля на закон
дисперсии поверхностных волн, приводящих к потерям УХН в ловушке из-за
их неупругого рассеяния на риплонах.
