Spontaneous creation and persistence of ground-state coherence in a resonantly driven intra-cavity atomic ensemble
D. G. Norris, A. D. Cimmarusti, L. A. Orozco +2
The spontaneous creation and persistence of ground-state coherence in an ensemble of intracavity Rb atoms has been observed as a quantum beat. Our system realizes a quantum eraser,…
Blackbody radiation shift in the Sr optical atomic clock
M. S. Safronova, S. G. Porsev, U. I. Safronova +2
We evaluated the static and dynamic polarizabilities of the 5s^2 ^1S_0 and 5s5p ^3P_0^o states of Sr using the high-precision relativistic configuration interaction + all-order met…
Feshbach spectroscopy of an ultracold mixture of Rb and Cs
Hung-Wen Cho, Daniel J. McCarron, Michael P. Koppinger +7
We report the observation of interspecies Feshbach resonances in an optically trapped mixture of Rb and Cs. We measure 14 interspecies features in the lowest spin ch…
Precision Measurement of Transition Matrix Elements via Light Shift Cancellation
C. D. Herold, V. D. Vaidya, X. Li +3
We present a method for accurate determination of atomic transition matrix elements at the 10^{-3} level. Measurements of the ac Stark (light) shift around "magic-zero" wavelengths…
Ytterbium in quantum gases and atomic clocks: van der Waals interactions and blackbody shifts
M. S. Safronova, S. G. Porsev, Charles W. Clark
We evaluated the C_6 coefficients of Yb-Yb and Yb -alkali/group II van der Waals interactions with 2% uncertainty. The only existing results for such quantities are for the Yb-Yb d…
Driven-dissipative dynamics of a strongly interacting Rydberg gas
A. W. Glaetzle, R. Nath, B. Zhao +2
We study the non-equilibrium many-body dynamics of a cold gas of ground state alkali atoms weakly admixed by Rydberg states with laser light. On a timescale shorter than the lifeti…
Magic wavelengths for optical cooling and trapping of lithium
M. S. Safronova, U. I. Safronova, Charles W. Clark
Using first-principles calculations, we identify magic wavelengths for the 2s-2p and 2s-3p transitions in lithium. The ns and np atomic levels have the same ac Stark shifts at the…
Sensitivity test of a blue-detuned dipole trap designed for parity non-conservation measurements in Fr
Dong Sheng, Jiehang Zhang, Luis A. Orozco
A dynamic blue-detuned optical dipole trap with stable atoms produces a differential ac Stark shift of 18 Hz in the ground state hyperfine transition, and it preserves th…
Polarizabilities of Si^{2+}: a benchmark test of theory and experiment
M. S. Safronova, S. G. Porsev, M. G. Kozlov +1
We have calculated electric-dipole polarizabilities of the 3s^2 ^1S_0, 3s3p ^3P_0, and 3s3p ^1P_1 states of the Si^{2+} ion using recently developed configuration interaction + all…
Anisotropy induced Feshbach resonances in a quantum dipolar gas of magnetic atoms
Alexander Petrov, Eite Tiesinga, Svetlana Kotochigova
We explore the anisotropic nature of Feshbach resonances in the collision between ultracold magnetic submerged-shell dysprosium atoms, which can only occur due to couplings to rota…
Controlled Production of Sub-Radiant States of a Diatomic Molecule in an Optical Lattice
Yosuke Takasu, Yutaka Saito, Yoshiro Takahashi +3
We report successful production of sub-radiant states of a two-atom system in a three-dimensional optical lattice starting from doubly occupied sites in a Mott insulator phase of a…
High flux cold Rubidium atomic beam for strongly coupled Cavity QED
Basudev Roy, Michael Scholten
This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity QED experiments in the regime of strong coupling. A 2 MOT, load…
Towards the production of ultracold ground-state RbCs molecules: Feshbach resonances, weakly bound states, and coupled-channel model
Tetsu Takekoshi, Markus Debatin, Raffael Rameshan +8
We have studied interspecies scattering in an ultracold mixture of Rb and Cs atoms, both in their lowest-energy spin states. The three-body loss signatures of 30 inc…
