Interaction of trapped ions with trapped atoms
… MOT. We demonstrate the first collisions between trapped atoms and trapped ions in the Langevin collision regime between Yb+ and Yb. A measurement of the Langevin rate constant through charge-exchange collisions between [alpha]Yb+ and [beta]Yb over three orders of magnitude in collision energy …

Lady Mary Wortley Montagu: the Trapped 'Other'
Lady Mary Wortley Montagu's letters have been widely read and recognized for their early contribution to feminist literature; however, critics have also defined her masculine persona as contradictory to her overall feminist leanings. Using Mikhail Bahktin's theories on the relationship between …

Inertial measurement via dynamics of trapped particles
… The insight motivating this approach is that a trapped particle acts like a mass on a spring, but the restoring forces are provided by electrostatic fields. Exquisitely machined physical mechanisms can be replaced by carefully tuned mechanical physics. Such inertial sensors could be simpler to …

Higher Order Trapped Lee Waves in the Stratosphere
… have posited the existence of higher-order trapped wave modes. Although the higher-order modes in these studies were confined to the troposphere due to the studies’ theoretical setup, Corby and Wallington (1956) demonstrate that the level of maximum amplitude for higher-order modes in a …

Dynamics of impurities and trapped Bose-Einstein Condensates
… investigate designing the confinement of tightly trapped impurities in a BEC reservoir to study their dissipative dynamics, and to study non-equilibrium dynamics of BECs confined in a tilted ring trap (both with ultracold atoms and polaritons).;In the first part we explore tightly confined …

An ultrasonic study of trapped hydrogen in niobium
… a model for the configuration of hydrogen trapped at interstitial oxygen or nitrogen impurities in BCC metals. Such a model would 'be important for an understanding of the physical properties of such systems, particularly of the quantum diffusion effects which occur. A review of all the …
