ультрахолоднi фермi-гази, резонанси Фешбаха, тричастинкова рекомбiнацiя

Анотація

За допомогою спектроскопiї Фешбаха з високою роздiльною здатнiстю дослiджено вироджений поляризований за спiном фермi-газ iз атомiв 161Dy та вимiряно втрати на тричастинкову рекомбiнацiю в слабких магнiтних полях. Для поля бiля 1 Гс знайдено 44 резонанснi особливостi. Також спостерiгаються плато з дуже низькими втратами. Для чотирьох типових резонансiв вивчено залежнiсть коефiцiєнта швидкостi тричастинкової рекомбiнацiї вiд розладування резонанса змiною магнiтного поля i вiд температури. Спостерiгалося значне зменшення втрат зi зменшенням температури вже при малих вiдхиленнях вiд резонансу. Опис складної поведiнки тричастинкових втрат в фермiонному 161Dy є важливим для його подальшого використання в дослiдженнях атомних квантових газiв.
