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…
Design and Performance of a Heated Gas Injector for Producing Cold Molecular Beams
Avneesh Verma, Jack Mango, Shungo Fukaya +4
We realize an injector device that supplies warm gas directly into a cryogenic environment. This injector has several advantageous features, including robustness, rigidity, simple…
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…
Thermal Emission of Strontium in a Cryogenic Buffer Gas Beam Source
Andrew Winnicki, Zack D. Lasner, John M. Doyle
We demonstrate production of cold atomic strontium (Sr) and strontium-containing molecules (SrOH) in a cryogenic buffer gas beam source via direct heating of strontium oxide (SrO)…
Pathway Towards Optical Cycling and Laser Cooling of Functionalized Arenes
Debayan Mitra, Zack D. Lasner, Guo-Zhu Zhu +8
Rapid and repeated photon cycling has enabled precision metrology and the development of quantum information systems using a variety of atoms and simple molecules. Extending optica…
