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…

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…

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…
