Quantum-State Controlled Chemical Reactions of Ultracold KRb Molecules
S. Ospelkaus, K. -K. Ni, D. Wang +7
How does a chemical reaction proceed at ultralow temperatures? Can simple quantum mechanical rules such as quantum statistics, single scattering partial waves, and quantum threshol…
Universal rate constants for reactive collisions of ultracold molecules
Zbigniew Idziaszek, Paul S. Julienne
A simple quantum defect model gives analytic expressions for the complex scattering length and threshold collision rates of ultracold molecules. If the probability of reaction in t…
A multi-photon magneto-optical trap
Saijun Wu, Thomas Plisson, Roger Brown +2
We demonstrate a Magneto-Optical Trap (MOT) configuration which employs optical forces due to light scattering between electronically excited states of the atom. With the standard…
Search for the electric dipole moment of the electron with thorium monoxide
Amar C. Vutha, Wesley C. Campbell, Yulia V. Gurevich +8
The electric dipole moment of the electron (eEDM) is a signature of CP-violating physics beyond the Standard Model. We describe an ongoing experiment to measure or set improved lim…
Precision measurement of the lifetime of the 6p 2P_1/2 level of Yb+
S. Olmschenk, D. Hayes, D. N. Matsukevich +4
We present a precise measurement of the lifetime of the 6p 2P_1/2 excited state of a single trapped ytterbium ion (Yb+). A time-correlated single-photon counting technique is used,…
Raman processes and effective gauge potentials
I. B. Spielman
A new technique is described by which light-induced gauge potentials allow systems of ultra-cold neutral atoms to behave like charged particles in a magnetic field. Here, atoms mov…
