Adiabaticity and localization in one-dimensional incommensurate lattices
E. E. Edwards, M. Beeler, Tao Hong +1
We experimentally investigate the role of localization on the adiabaticity of loading a Bose-Einstein condensate into a one-dimensional optical potential comprised of a shallow pri…
Observation of an ultracold plasma instability
X. L. Zhang, R. S. Fletcher, S. L. Rolston
We present the first observation of an instability in an expanding ultracold plasma. We observe periodic emission of electrons from an ultracold plasma in weak, crossed magnetic an…
Using Charged Particle Imaging to Study Ultracold Plasma Expansion
X. L. Zhang, R. S. Fletcher, S. L. Rolston
We develop a projection imaging technique to study ultracold plasma dynamics. We image the charged particle spatial distributions by extraction with a high-voltage pulse onto a pos…
Ultracold Plasma Expansion in a Magnetic Field
X. L. Zhang, R. S. Fletcher, S. L. Rolston +2
We measure the expansion of an ultracold plasma across the field lines of a uniform magnetic field. We image the ion distribution by extracting the ions with a high voltage pulse o…
