Producing high densities of molecules is a fundamental challenge for low-temperature, ion-molecule reaction studies. Traveling-wave Stark decelerators promise to deliver high density beams of cold, polar molecules but require non-trivial control of h

From Hot Beams to Trapped Ultracold Molecules: Motivations, Methods and Future Directions

Autor: M. R. Tarbutt, Noah Fitch

Publikováno v: Molecular Beams in Physics and Chemistry ISBN: 9783030639624

Over the past century, the molecular beam methods pioneered by Otto Stern have advanced our knowledge and understanding of the world enormously. Stern and his colleagues used these new techniques to measure the magnetic dipole moments of fundamental

The electric dipole moment of the electron (eEDM) can be measured with high precision using heavy polar molecules. In this paper, we report on a series of new techniques that have improved the statistical sensitivity of the YbF eEDM experiment. We in

Long Rotational Coherence Times of Molecules in a Magnetic Trap

Publikováno v: Physical Review Letters, 2020, Vol.124(6), pp.063001 [Peer Reviewed Journal]

Polar molecules in superpositions of rotational states exhibit long-range dipolar interactions, but maintaining their coherence in a trapped sample is a challenge. We present calculations that show many laser-coolable molecules have convenient rotati

We demonstrate coherent microwave control of the rotational, hyperfine and Zeeman states of ultracold CaF molecules, and the magnetic trapping of these molecules in a single, selectable quantum state. We trap about $5\times 10^{3}$ molecules for 2 s
