Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
Lifetime measurement of the 5dD state in Ba
Amita Mohanty, Elwin A. Dijck, Mayerlin Nuñez Portela +5
The lifetime of the metastable 5dD state has been measured for a single trapped Ba ion in a Paul trap in Ultra High Vacuum (UHV) in the 10 mbar pressure ran…
High-precision spectroscopy of ultracold molecules in an optical lattice
B. H. McGuyer, M. McDonald, G. Z. Iwata +4
The study of ultracold molecules tightly trapped in an optical lattice can expand the frontier of precision measurement and spectroscopy, and provide a deeper insight into molecula…
A Mixture of Bose and Fermi Superfluids
Igor Ferrier-Barbut, Marion Delehaye, Sebastien Laurent +5
Superconductivity and superfluidity of fermionic and bosonic systems are remarkable many-body quantum phenomena. In liquid helium and dilute gases, Bose and Fermi superfluidity has…
Λ-enhanced Sub-Doppler Cooling of Lithium Atoms in D1 Gray Molasses
Andrew T. Grier, Igor Ferrier-Barbut, Benno S. Rem +4
Following the bichromatic sub-Doppler cooling scheme on the D1 line of 40K recently demonstrated in (Fernandes et al. 2012), we introduce a similar technique for 7Li atoms and obta…
One-dimensional array of ion chains coupled to an optical cavity
Marko Cetina, Alexei Bylinskii, Leon Karpa +7
We present a novel hybrid system where an optical cavity is integrated with a microfabricated planar-electrode ion trap. The trap electrodes produce a tunable periodic potential al…
Lifetime of the Bose Gas with Resonant Interactions
B. S. Rem, A. T. Grier, I. Ferrier-Barbut +8
We study the lifetime of a Bose gas at and around unitarity using a Feshbach resonance in lithium~7. At unitarity, we measure the temperature dependence of the three-body decay coe…
Micromotion-induced Limit to Atom-Ion Sympathetic Cooling in Paul Traps
Marko Cetina, Andrew T. Grier, Vladan Vuletić
We present and derive analytic expressions for a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done…
Interaction between Atomic Ensembles and Optical Resonators: Classical Description
Haruka Tanji-Suzuki, Ian D. Leroux, Monika H. Schleier-Smith +4
Many effects in the interaction between atoms and a cavity that are usually de-scribed in quantum mechanical terms (cavity quantum electrodynamics, cavity QED) can be understood an…
Observation of Cold Collisions between Trapped Ions and Trapped Atoms
Andrew T. Grier, Marko Cetina, Fedja Oručević +1
We demonstrate a double-trap system well suited to study cold collisions between trapped ions and trapped atoms. Using Yb ions confined in a Paul trap and Yb atoms in a magneto…
Bright Source of Cold Ions for Surface-Electrode Traps
Marko Cetina, Andrew Grier, Jonathan Campbell +2
We produce large numbers of low-energy ions by photoionization of laser-cooled atoms inside a surface-electrode-based Paul trap. The isotope-selective trap loading rate of $4\times…
