Sr lattice clock with inaccuracy below 10
Martin M. Boyd, Andrew D. Ludlow, Sebastian Blatt +4
Aided by ultra-high resolution spectroscopy, the overall systematic uncertainty of the - clock resonance for lattice-confined Sr has been characterized…
Coherent Quantum Engineering of Free-Space Laser Cooling
Josh W. Dunn, J. W. Thomsen, Chris H. Greene +1
We perform a quantitative analysis of the cooling dynamics of three-level atomic systems interacting with two distinct lasers. Employing sparse-matrix techniques, we find numerical…
Dynamic cancellation of ac Stark shift for pulsed EIT/Raman optical lattice clocks
T. Zanon-Willette, A. D. Ludlow, S. Blatt +3
We propose a combination of Electromagnetically Induced Transparency (EIT)/Raman and pulsed spectroscopy techniques to accurately cancel frequency shifts arising from EIT fields in…
Experimental verification of minima in excited long-range Rydberg states of Rb_2
Chris H. Greene, Edward L. Hamilton, Heather Crowell +2
Recent theoretical studies with alkali atoms A excited to high Rydberg states predicted the existence of ultra long-range molecular bound states. Such excited dimers have…
Cold collisions of OH and Rb. I: the free collision
Manuel Lara, John L. Bohn, Daniel E. Potter +2
We have calculated elastic and state-resolved inelastic cross sections for cold and ultracold collisions in the Rb() + OH() system, including fine-structure and h…
OH hyperfine ground state: from precision measurement to molecular qubits
Benjamin L. Lev, Edmund R. Meyer, Eric R. Hudson +3
We perform precision microwave spectroscopy--aided by Stark deceleration--to reveal the low magnetic field behavior of OH in its ^2Π_{3/2} ro-vibronic ground state, identifying two…
Near threshold rotational excitation of molecular ions by electron-impact
A. Faure, V. Kokoouline, Chris H. Greene +1
New cross sections for the rotational excitation of H by electrons are calculated {\it ab initio} at low impact energies. The validity of the adiabatic-nuclei-rotation (ANR)…
Measurement of the Temperature Dependence of the Casimir-Polder Force
J. M. Obrecht, R. J. Wild, M. Antezza +3
We report on the first measurement of a temperature dependence of the Casimir-Polder force. This measurement was obtained by positioning a nearly pure 87-Rb Bose-Einstein condensat…
Ultracold Rb-OH collisions and prospects for sympathetic cooling
M. Lara, J. L. Bohn, D. Potter +2
We have computed ab inito cross sections for cold collisions of Rb atoms with OH radicals. We predict collision rate constants of order 10^{-11} cm^3/s at temperatures in the range…
Candidate molecular ions for an electron electric dipole moment experiment
Edmund R. Meyer, John L. Bohn, Michael P. Deskevich
This paper is a theoretical work in support of a newly proposed experiment (R. Stutz and E. Cornell, Bull. Am. Soc. Phys. 89, 76 2004) that promises greater sensitivity to measurem…
Narrow Line Photoassociation in an Optical Lattice
T. Zelevinsky, M. M. Boyd, A. D. Ludlow +5
With ultracold Sr in a 1D magic wavelength optical lattice, we performed narrow line photoassociation spectroscopy near the SP intercombination transition.…
High resolution atomic coherent control via spectral phase manipulation of an optical frequency comb
Matthew C. Stowe, Flavio C. Cruz, Jun Ye
We demonstrate high resolution coherent control of cold atomic Rubidium utilizing spectral phase manipulation of a femtosecond optical frequency comb. Transient coherent accumulati…
Renner-Teller effects in HCO+ dissociative recombination
Ivan A. Mikhaylov, Viatcheslav Kokoouline, Asa Larson +2
A theoretical description of the dissociative recombination process for the HCO+ ion suggests that the nonadiabatic Renner-Teller coupling between electronic and vibrational degree…
Cold Molecule Spectroscopy for Constraining the Evolution of the Fine Structure Constant
Eric R. Hudson, H. J. Lewandowski, Brian C. Sawyer +1
We report precise measurements of ground-state, -doublet microwave transitions in the hydroxyl radical molecule (OH). Utilizing slow, cold molecules produced by a Stark decelera…
