Coherent Manipulation of the Internal State of Ultracold RbCs Molecules with Multiple Microwave Fields
Jacob A. Blackmore, Philip D. Gregory, Sarah L. Bromley +1
We explore coherent multi-photon processes in RbCs molecules using 3-level lambda and ladder configurations of rotational and hyperfine states, and discuss their rel…
Controlling the ac Stark effect of RbCs with dc electric and magnetic fields
Jacob A. Blackmore, Rahul Sawant, Philip D. Gregory +4
We investigate the effects of static electric and magnetic fields on the differential ac Stark shifts for microwave transitions in ultracold bosonic RbCs molecules,…
Optical Atomic Clock Comparison through Turbulent Air
Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32
We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Loss of ultracold RbCs molecules via optical excitation of long-lived two-body collision complexes
Philip D. Gregory, Jacob A. Blackmore, Sarah L. Bromley +1
We show that the lifetime of ultracold ground-state RbCs molecules in an optical trap is limited by fast optical excitation of long-lived two-body collision complexe…
