Collapse and revival of the monopole mode of a degenerate Bose gas in an isotropic harmonic trap
C. J. E. Straatsma, V. E. Colussi, M. J. Davis +5
We study the monopole (breathing) mode of a finite temperature Bose-Einstein condensate in an isotropic harmonic trap recently developed by Lobser et al. [Nat.~Phys., \textbf{11},…
Precision Spectroscopy of Polarized Molecules in an Ion Trap
Huanqian Loh, Kevin C. Cossel, Matt Grau +5
Polar molecules are desirable systems for quantum simulations and cold chemistry. Molecular ions are easily trapped, but a bias electric field applied to polarize them tends to acc…
Photon Counting for Bragg Spectroscopy of Quantum Gases
J. M. Pino, R. J. Wild, P. Makotyn +2
We demonstrate a photon-counting technique for detecting Bragg excitation of an ultracold gas of atoms. By measuring the response of the light field to the atoms, we derive a signa…
Observation of the Presuperfluid Regime in a Two-Dimensional Bose Gas
S. Tung, G. Lamporesi, D. Lobser +2
In complementary images of coordinate-space and momentum-space density in a trapped 2D Bose gas, we observe the emergence of pre-superfluid behavior. As phase-space density inc…
Bragg spectroscopy of a strongly interacting 85Rb Bose-Einstein condensate
S. B. Papp, J. M. Pino, R. J. Wild +4
We report on measurements of the excitation spectrum of a strongly interacting Bose-Einstein condensate (BEC). A magnetic-field Feshbach resonance is used to tune atom-atom interac…
Measuring Electric Fields From Surface Contaminants with Neutral Atoms
J. M. Obrecht, R. J. Wild, E. A. Cornell
In this paper we demonstrate a technique of utilizing magnetically trapped neutral Rb-87 atoms to measure the magnitude and direction of stray electric fields emanating from surfac…
