Wafer-scale fabrication of evacuated alkali vapor cells
Yang Li, Donggyu B. Sohn, Matthew Hummon +2
We describe a process for fabricating a wafer-scale array of alkali metal vapor cells with low residual gas pressure. We show that by etching long, thin channels between the cells…
High-performance, compact optical standard
Zachary L. Newman, Vincent Maurice, Connor Fredrick +6
We describe a high-performance, compact optical frequency standard based on a microfabricated Rb vapor cell and a low-noise, external cavity diode laser operating on the Rb two-pho…
Universal methods for suppressing the light shift in atomic clocks using power modulation
V. I. Yudin, M. Yu. Basalaev, A. V. Taichenachev +8
We show that the light shift in atomic clocks can be suppressed using time variation of the interrogation field intensity. By measuring the clock output at two intensity levels, er…
Photonic integration of an optical atomic clock
Z. L. Newman, V. Maurice, T. E. Drake +19
Laboratory optical atomic clocks achieve remarkable accuracy (now counted to 18 digits or more), opening possibilities to explore fundamental physics and enable new measurements. H…
Microresonator Brillouin Laser Stabilization Using a Microfabricated Rubidium Cell
William Loh, Matthew T. Hummon, Holly F. Leopardi +5
We frequency stabilize the output of a miniature stimulated Brillouin scattering (SBS) laser to rubidium atoms in a microfabricated cell to realize a laser system with frequency st…
Prospects for a Narrow Line MOT in YO
Alejandra L. Collopy, Matthew T. Hummon, Mark Yeo +2
In addition to being suitable for laser cooling and trapping in a magneto-optical trap (MOT) using a relatively broad (5 MHz) transition, the molecule YO possesses a narrow-l…
Rotational state microwave mixing for laser cooling of complex diatomic molecules
Mark Yeo, Matthew T. Hummon, Alejandra L. Collopy +5
We demonstrate the mixing of rotational states in the ground electronic state using microwave radiation to enhance optical cycling in the molecule yttrium (II) monoxide (YO). This…
Continuous all-optical deceleration and single-photon cooling of molecular beams
A. M. Jayich, A. C. Vutha, M. T. Hummon +2
Ultracold molecular gases are promising as an avenue to rich many-body physics, quantum chemistry, quantum information, and precision measurements. This richness, which flows from…
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…
New Limits on Local Lorentz Invariance in Mercury and Cesium
S. K. Peck, D. K. Kim, D. Stein +4
We report new bounds on Local Lorentz Invariance (LLI) violation in Cs and Hg. The limits are obtained through the observation of the the spin- precession frequencies of 199Hg and…
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…
Cold N+NH Collisions in a Magnetic Trap
Matthew T. Hummon, Timur V. Tscherbul, Jacek Kłos +5
We present an experimental and theoretical study of atom-molecule collisions in a mixture of cold, trapped atomic nitrogen and NH molecules at a temperature of ~mK. We me…
Cold heteromolecular dipolar collisions
Brian C. Sawyer, Benjamin K. Stuhl, Mark Yeo +7
We present the first experimental observation of cold collisions between two different species of neutral polar molecules, each prepared in a single internal quantum state. Combini…

We report a combined experimental and theoretical study of collision-induced dipolar relaxation in a cold spin-polarized gas of atomic nitrogen (N). We use buffer gas cooling to cr…
Magnetic trapping of atomic nitrogen (14^N) and cotrapping of NH (X-triplet-Sigma-)
Matthew T. Hummon, Wesley C. Campbell, Hsin-I Lu +3
We observe magnetic trapping of atomic nitrogen (14^N) and cotrapping of ground state imidogen (14^NH, X-triplet-Sigma-). Both are loaded directly from a room temperature beam via…
