Order of Magnitude Improved Optical Trapping of Molecules Through Transverse Cooling
Abdullah Nasir, Annika Lunstad, Mingda Li +5
We demonstrate a two-dimensional Sisyphus laser cooling method that increases the number of strontium monohydroxide (SrOH) molecules loaded into a magneto-optical trap by a factor…
A cryogenic buffer gas beam source with in-situ ablation target replacement
Zhen Han, Zack Lasner, Collin Diver +11
The design and performance of a cryogenic buffer gas beam (CBGB) source with a load-lock system is presented. The ACME III electron electric dipole moment (eEDM) search experiment…
Hyperfine-Resolved Spectroscopy of Dysprosium Monoxide (DyO) for Precision Measurements of the Nuclear Schiff Moment
Zack D. Lasner, Aidan T. Ohl, Nicole M. Albright +5
We perform laser spectroscopy of dysprosium monoxide (DyO) to determine the hyperfine structure of the ground X8 and excited [17.1]7 states in the Dy and Dy isotopo…
High-sensitivity molecular spectroscopy of SrOH using magneto-optical trapping
Annika Lunstad, Hiromitsu Sawaoka, Zack Lasner +5
Polyatomic molecules are projected to be powerful tools in searches for physics beyond the Standard Model (BSM), including new CP-violating (CPV) interactions and ultralight dark m…
Optical Trapping of SrOH Molecules for Dark Matter and T-violation Searches
Hiromitsu Sawaoka, Abdullah Nasir, Annika Lunstad +4
We report an optical dipole trap of strontium monohydroxide (SrOH) with 1400(300) trapped molecules. Through optical pumping, we access vibrational states that are proposed for imp…
