Probing the electron EDM with cold molecules [PDF]

, 2006
We present progress towards a new measurement of the electron electric dipole moment using a cold supersonic beam of YbF molecules. Data are currently being taken with a sensitivity of $10^{-27}\textrm{e.cm}/\sqrt{\textrm{day}}$.

Deceleration of neutral molecules in macroscopic traveling traps [PDF]

, 2010
A new type of decelerator is presented where polar neutral molecules are guided and decelerated using the principle of traveling electric potential wells, such that molecules are confined in stable three-dimensional traps throughout. This new decelerator

Precision measurement of the rotational energy-level structure of the three-electron molecule He$_2^+$

, 2016
The term values of all rotational levels of the $^4$He${_2}^+\,X^+\,^2\Sigma_u^+\,(\nu^+=0)$ ground vibronic state with rotational quantum number $N^+\le 19$ have been determined with an accuracy of 8 x 10$^{-4}$ cm$^{-1}$ ($\sim{25}$ MHz) by MQDT ...

Bichromatic Slowing of Metastable Helium

, 2012
We examine two approaches for significantly extending the velocity range of the optical bichromatic force (BCF), to make it useful for laser deceleration of atomic and molecular beams.

Methods for Zeeman-Sisyphus deceleration of heavy polar molecules

, 2023
Zeeman-Sisyphus deceleration (ZS, ZSD) is a method for slowing polar molecules while scattering only a small number of photons when compared with direct laser cooling. It also ensures that molecules are transversely confined by application of transverse magnetic field gradients. It has applications in ensuring that a wider range of molecules, including

Laser slowing of CaF molecules to near the capture velocity of a molecular MOT [PDF]

, 2016
Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap (MOT) for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened "white-light" slowing and observe approximately 6x10^4 ...

Zeeman deceleration of methyl radical

, 2014
Conventional Zeeman decelerator, consisting of 80 stages, was constructed and tested. The experimental setup was characterized using O₂ as the reference molecule. Known results of deceleration of O₂ were reproduced. As an extension, detailed REMPI analysis of deceleration of O₂ was carried out, this REMPI analysis was conducted in parallel with ref [1].

Nonadiabatic transitions in a Stark decelerator

, 2010
In a Stark decelerator, polar molecules are slowed down and focussed by an inhomogeneous electric field which switches between two configurations.

Stark deceleration of CaF molecules in strong- and weak-field seeking states

, 2011
We report the Stark deceleration of CaF molecules in the strong-field seeking ground state and in a weak-field seeking component of a rotationally-excited state. We use two types of decelerator, a conventional Stark decelerator for the weak-field seekers,
