Bad weather delays launch of NASA's Psyche mission

(Josh Dinner)

As Wednesday night's storms blew in, the decision was made to forgo Thursday's launch attempt to capitalize on the better weather on Friday and Saturday.

Уважаемые коллеги!

На заседании Ученого совета в пятницу 13 октября в 11:30 будут заслушаны
2 доклада:

1) _Владимир Парфеньев_, Евгений Могилевский, Григорий Фалькович
*Sum-of-squares bounds on correlation functions in a minimal model of
turbulence*

We suggest a new computer-assisted approach to the development of
turbulence theory. It allows one to impose lower and upper bounds on
correlation functions using sum-of-squares polynomials. We demonstrate
it on the minimal cascade model of two resonantly interacting modes,
when one is pumped and the other dissipates. We show how to present
correlation functions of interest as part of a sum-of-squares polynomial
using the stationarity of the statistics. That allows us to find how the
moments of the mode amplitudes depend on the degree of non-equilibrium
(analog of the Reynolds number), which reveals some properties of
marginal statistical distributions. By combining scaling dependence with
the results of direct numerical simulations, we obtain the probability
densities of both modes in a highly intermittent inverse cascade. We
also show that the relative phase between modes tends to π/2 and -π/2 in
the direct and inverse cascades as the Reynolds number tends to
infinity, and derive bounds on the phase variance. Our approach combines
computer-aided analytical proofs with a numerical algorithm applied to
high-degree polynomials.

2) _Н.А. Степанов_, М.А. Скворцов
*Электрон-фононное взаимодействие в модели гранулированной пленки*

Мы изучаем электрон-фононную релаксацию в модели гранулированной
металлической пленки, где зерна образованы регулярно расположенными
потенциальными барьерами произвольной прозрачности. Рассчитана скорость
релаксации акустических фононов в модели Дебая с учетом двух механизмов
электрон-фононного рассеяния: стандартного взаимодействия деформации
решетки с электронной плотностью и взаимодействия за счет смещения
границ зерен, вызванного колебаниями решетки. При самых низких
температурах мощность электронно-фононного охлаждения соответствует
степенной зависимости по температуре, типичной для чистых систем, но с
коэффициентом, растущим по мере уменьшения прозрачности границ зерен.

При числе желающих больше 5 будет организован автобус.
Для записи на автобус из Москвы в Черноголовку необходимо до 18:00
четверга отправить письмо на адрес электронной почты bus@itp.ac.ru
После этого записавшимся до 20:00 поступит подтверждение об отправке или
неотправке автобуса в зависимости от числа записавшихся.
Запись на обратный автобус - на Ученом совете.
