Photon Cycling and Laser Cooling of an Asymmetric Top Molecule
Grace K. Li, Giseok Lee, Jack Mango +8
We realize two-dimensional magnetically-assisted Sisyphus laser cooling of an asymmetric top molecule (ATM), calcium monoamide (CaNH). Vibrational state closure is achieved wit…
Optical cycling on thorium monoxide (ThO) for an improved test of fundamental symmetries
Alexander Frenett, Dorothy Gan, Nicholas Emtage +3
Optical cycling refers to repeated excitation and spontaneous emission on an electronic transition in an atom or molecule. Optical cycling in molecules can enable a wide range of q…
Magneto-optical trapping of a heavy polyatomic molecule for precision measurement
Zack D. Lasner, Alexander Frenett, Hiromitsu Sawaoka +10
We report a magneto-optical trap of strontium monohydroxide (SrOH) containing 2000(600) molecules at a temperature of 1.2(3) mK. The lifetime is 91(9) ms, which is limited by decay…
Vibrational Branching Ratios for Laser-Cooling of Nonlinear Strontium-Containing Molecules
Alexander Frenett, Zack Lasner, Lan Cheng +1
The vibrational branching ratios from the lowest excited electronic state for , , and are measured at the level. Spectr…
Zeeman-Sisyphus Deceleration for Heavy Molecules with Perturbed Excited-State Structure
Hiromitsu Sawaoka, Alexander Frenett, Abdullah Nasir +4
We demonstrate and characterize Zeeman-Sisyphus (ZS) deceleration of a beam of ytterbium monohydroxide (YbOH). Our method uses a combination of large magnetic fields ( 2.5 T)…
Zeeman-Sisyphus Deceleration of Molecular Beams
Benjamin L. Augenbraun, Alexander Frenett, Hiromitsu Sawaoka +5
We present a robust, continuous molecular decelerator that employs high magnetic fields and few optical pumping steps. CaOH molecules are slowed, accumulating at low velocities in…
Observation and laser spectroscopy of ytterbium monomethoxide, YbOCH
Benjamin L. Augenbraun, Zack D. Lasner, Alexander Frenett +4
We describe a laser spectroscopic study of ytterbium monomethoxide, YbOCH, a species of interest to searches for time-reversal symmetry violation using laser-cooled molecules.…
Laser-Cooled Polyatomic Molecules for Improved Electron Electric Dipole Moment Searches
Benjamin L. Augenbraun, Zack D. Lasner, Alexander Frenett +4
Doppler and Sisyphus cooling of YbOH are achieved and studied. This polyatomic molecule has high sensitivity to physics beyond the Standard Model and represents a new class…
Two-photon vibrational transitions in as probes of variation of the proton-to-electron mass ratio
Ryan Carollo, Alexander Frenett, David Hanneke
Vibrational overtones in deeply bound molecules are sensitive probes for variation of the proton-to-electron mass ratio . In nonpolar molecules, these overtones may be driven as…
