Magneto-optical trapping forces for molecules are far weaker than for alkali-metal atoms because the photon scattering rate is reduced when there are multiple ground states, and because of optical pumping into dark states. The force is further reduced when the upper state has a much smaller Zeeman splitting than the lower state. We use a rate model to estimate the strength of the trapping and damping forces in a magneto-optical trap (MOT) of CaF molecules, using either the A 2 1/2–X 2…

Magneto-optical trapping of diatomic molecules

Magneto-optical trapping of diatomic molecules Eric B. Norrgard 2016 Laser cooling in a magneto-optical trap (MOT) is the workhorse technique for atomic physics in the ultracold regime, serving as

Characteristics of a magneto-optical trap of molecules

We present the properties of a magneto-optical trap (MOT) of CaF molecules. We study the process of loading the MOT from a decelerated buffer-gas-cooled beam, and how best to slow this molecular beam

Blue-Detuned Magneto-Optical Trap.

The properties and advantages of a new magneto-optical trap where blue-detuned light drives "type-II" transitions that have dark ground states are presented, making the blue- Detuned MOT particularly attractive for molecular MOTs, which rely on type-II transitions.

Maximizing the capture velocity of molecular magneto-optical traps with Bayesian optimization

Magneto-optical trapping (MOT) is a key technique on the route towards ultracold molecular ensembles. However, the realization and optimization of magneto-optical traps with their wide parameter

Laser cooling and magneto-optical trapping of molecules analyzed using optical Bloch equations and the Fokker-Planck-Kramers equation

We study theoretically the behavior of laser-cooled calcium monofluoride (CaF) molecules in an optical molasses and magneto-optical trap (MOT), and compare our results to recent experiments. We use

Molecules cooled below the Doppler limit

Magneto-optical trapping and sub-Doppler cooling of atoms has been instrumental for research in ultracold atomic physics. This regime has now been reached for a molecular species, CaF.

We present a theoretical study of magneto-optical trapping (MOT) force exerted on magnesium monofluoride (MgF) with 3D rate equations, in which we have considered the complex vibrational and

Methods for measuring the electron’s electric dipole moment using ultracold YbF molecules

Measurements of the electron’s electric dipole moment (eEDM) are demanding tests of physics beyond the standard model. We describe how ultracold YbF molecules could be used to improve the precision
