A high-accuracy optical clock via three-level coherence in neutral bosonic Sr
Robin Santra, Ennio Arimondo, Tetsuya Ido +2
An optical atomic clock scheme is developed that utilizes two lasers to establish coherent coupling between the ground state of Sr and the first excit…
Influence of magnetic fields on cold collisions of polar molecules
Christopher Ticknor, John L. Bohn
We consider cold collisions of OH molecules in the grounds state, under the influnce of a magnetic field. We find that modest fields of several thousand gauss can act t…
Precision spectroscopy and density-dependent frequency shifts in ultracold Sr
Tetsuya Ido, Thomas H. Loftus, Martin M. Boyd +3
By varying the density of an ultracold Sr sample from cm to cm, we make the first definitive measurement of the density-related frequency sh…
Ultracold Collisions of Fermionic OD Radicals
A. V. Avdeenkov, J. L. Bohn
We discuss consequences of Fermi exchange symmetry on collisions of polar molecules at low temperatures (below 1 K), considering the OD radical as a prototype. At low fields and lo…
Multiphoton ionization of xenon in the VUV regime
Robin Santra, Chris H. Greene
In a recent experiment at the VUV free-electron laser facility at DESY in Hamburg, the generation of multiply charged ions in a gas of atomic xenon was observed. This paper develop…
Siegert pseudostates: completeness and time evolution
Robin Santra, Jeffrey M. Shainline, Chris H. Greene
Within the theory of Siegert pseudostates, it is possible to accurately calculate bound states and resonances. The energy continuum is replaced by a discrete set of states. Many qu…
High efficiency symmetric beam splitter for cold atoms with a standing wave light pulse sequence
Saijun Wu, Yingju Wang, Quentin Diot +1
In a recent experiment [1], it was observed that a sequence of two standing wave square pulses can split a BEC at rest into +/- 2 h_bar k diffraction orders with almost 100% effici…
Narrow Line Cooling and Momentum-Space Crystals
Thomas H. Loftus, Tetsuya Ido, Martin M. Boyd +2
Narrow line laser cooling is advancing the frontier for experiments ranging from studies of fundamental atomic physics to high precision optical frequency standards. In this paper,…
Efficient Stark deceleration of cold polar molecules
Eric R. Hudson, J. R. Bochinski, H. J. Lewandowski +2
Stark deceleration has been utilized for slowing and trapping several species of neutral, ground-state polar molecules generated in a supersonic beam expansion. Due to the finite p…
A pulsed, low-temperature beam of supersonically cooled free radical OH molecules
H. J. Lewandowski, Eric R. Hudson, J. R. Bochinski +1
An improved system for creating a pulsed, low-temperature molecular beam of OH radicals has been developed. We use a pulsed discharge to create OH from HO seeded in Xe during a…
Cold free radical molecules in the laboratory frame
J. R. Bochinski, Eric R. Hudson, H. J. Lewandowski +1
A special class of molecules that are important to many subfields in molecular dynamics and chemical physics, namely free radical molecules, now enjoy a significant degree of cente…
Photofragmentation of the H_3 molecule, including Jahn-Teller coupling effects
Viatcheslav Kokoouline, Chris H. Greene
We have developed a theoretical method for interpretation of photoionization experiments with the H_3 molecule. In the present study we give a detailed description of the method, w…
Narrow Line Cooling: Finite Photon Recoil Dynamics
Thomas H. Loftus, Tetsuya Ido, Andrew D. Ludlow +2
We present an extensive study of the unique thermal and mechanical dynamics for narrow-line cooling on the 1S0 - 3P1 88Sr transition. For negative detuning, trap dynamics reveal a…
