SIGN UP ⋅   WEBSITE   The Launchpad Relativity Space's 3D-printed rocket fails to reach orbit (Relativity Space) Relativity Space made history late Wednesday with the launch of Terran 1, the world's first 3D-printed rocket. But something went wrong with the rocket's upper stage. Still, the company is thrilled to have made it through Max-Q. "We just completed a major step in proving to the world that 3D-printed rockets are structurally viable," the company's Arwa Tizani Kelly said. Full Story: Space (3/22)  5 planets will align soon.

Space Deal of the Day Save $100 on this Lego Star Wars UCS Millennium Falcon (Future) Lego Star Wars fans and collectors can save themselves plenty of credits on this great deal as the UCS Lego Millennium Falcon is over $100 off at Amazon. It's a sizable discount on a sizable set. You can save $102 on this mammoth 7541-piece Lego set, bringing the price down to $747.36. We've reviewed the UCS Millennium Falcon and it is unquestionably one of the best Lego Star Wars sets on the market today, if not of all time.

A moderate aurora watch is in effect for Friday, March 24, in higher latitudes of Earth due to a coronal hole, an opening in the sun's magnetic field, according to the U.S. National Oceanic and Atmospheric Administration. Here's what to know.

Уважаемые коллеги!

На заседании Ученого совета в пятницу  24 марта в 11:30 будут заслушаны
2 доклада:

1) С.И. Матвеенко
*Туннелирование через примесный барьер в жидкости Латтинжера с
спин-орбитальным взаимодействием. *

Методами бозонизации и ренорм-группы исследованы эффекты
спин-орбитального взаимодействия (приводящие к нарушению разделения
спиновых и зарядовых степеней свободы) на туннелирование через примесный
барьер в одномерной модели Латтинжера. Найдены поправки к фазовой
диаграмме основного состояния, вычислен кондактанс в зависимости от
параметров Латтинжера и спин-орбитального взаимодействия.

2) С.И. Матвеенко
*Многочастичная локализация в одномерной фрустрированной XY-цепочке*

Эффекты многочастичной локализации исследовались в одномерной
фрустрированной XY- цепочке в случайном магнитном поле, с
взаимодействием ближайших, и через один, спинов. Найден численно переход
в состояние с многочастичной локализацией при увеличении амплитуды
случайного поля. Наличие делокализованной фазы при малой амплитуде
беспорядка анализируется аналитически, переходом к эквивалентному
представлению модели в терминах бесспиновых фермионов с эффективным
нелокальным взаимодействием.
