The Bose-Einstein Condensate and Cold Atom Laboratory
Kai Frye, Sven Abend, Wolfgang Bartosch +48
Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension and eliminates the…
Clean, Robust Alkali Sources by Intercalation within Highly-Oriented Pyrolytic Graphite
Rudolph N. Kohn, Matthew S. Bigelow, Mary Spanjers +6
We report the fabrication, characterization, and use of rubidium vapor dispensers based on highly-oriented pyrolytic graphite (HOPG) intercalated with metallic rubidium. Compared t…
Frequency Shifts due to Stark Effects on a Rb two-photon transition
Kyle W Martin, Benjamin Stuhl, Jon Eugenio +4
The two-photon transition in Rb is of interest for the development of a compact optical atomic clock. Here we present a rigorous calculation of the 7…
Compact Optical Atomic Clock Based on a Two-Photon Transition in Rubidium
Kyle W. Martin, Gretchen Phelps, Nathan D. Lemke +7
Extra-laboratory atomic clocks are necessary for a wide array of applications (e.g. satellite-based navigation and communication). Building upon existing vapor cell and laser techn…
Two-dimensional grating magneto-optical trap
Eric Imhof, Benjamin Stuhl, Brian Kasch +3
We demonstrate a two-dimensional grating magneto-optical trap (2D GMOT) with a single input cooling laser beam and a planar diffraction grating using Rb. This configuration…
Direct observation of Feshbach enhanced -wave scattering of fermions
Dina Genkina, Lauren M. Aycock, Benjamin K. Stuhl +3
We directly measured the normalized -wave scattering cross-section of ultracold atoms across a magnetic-field Feshbach resonance by colliding pairs of degener…
Evaporative cooling of the dipolar radical OH
Benjamin K. Stuhl, Matthew T. Hummon, Mark Yeo +3
Atomic physics was revolutionized by the development of forced evaporative cooling: it led directly to the observation of Bose-Einstein condensation, quantum-degenerate Fermi gases…
Magneto-optical trapping of diatomic molecules
Matthew T. Hummon, Mark Yeo, Benjamin K. Stuhl +3
The development of the magneto-optical trap revolutionized the fields of atomic and quantum physics by providing a simple method for the rapid production of ultracold, trapped atom…
Microwave state transfer and adiabatic dynamics of magnetically trapped polar molecules
Benjamin K. Stuhl, Mark Yeo, Brian C. Sawyer +2
Cold and ultracold polar molecules with nonzero electronic angular momentum are of great interest for studies in quantum chemistry and control, investigations of novel quantum syst…
Magneto-Optical Trap for Polar Molecules
Benjamin K. Stuhl, Brian C. Sawyer, Dajun Wang +1
We propose a method for laser cooling and trapping a substantial class of polar molecules, and in particular titanium (II) oxide (TiO). This method uses pulsed electric fields to n…
Low-energy molecular collisions in a permanent magnetic trap
Brian C. Sawyer, Benjamin K. Stuhl, Dajun Wang +2
Cold, neutral hydroxyl radicals are Stark decelerated and confined within a magnetic trap consisting of two permanent ring magnets. The OH molecules are trapped in the ro-vibration…
Mitigation of loss within a molecular Stark decelerator
Brian C. Sawyer, Benjamin K. Stuhl, Benjamin L. Lev +2
The transverse motion inside a Stark decelerator plays a large role in the total efficiency of deceleration. We differentiate between two separate regimes of molecule loss during t…
Magneto-electrostatic trapping of ground state OH molecules
Brian C. Sawyer, Benjamin L. Lev, Eric R. Hudson +4
We report the magnetic confinement of neutral, ground state hydroxyl radicals (OH) at a density of cm and temperature of 30 mK. An adjustable elect…
