Polarizability of ultracold molecules in the rovibrational ground state of
New Journal of Physics, 2015 We study, both theoretically and experimentally, the dynamical polarizability $\alpha (\omega )$ of ${\mathrm{Rb}}_{2}$ molecules in the rovibrational ground state of ${a}^{3}{\Sigma }_{u}^{+}$ .

Imaging Cold Molecules on a Chip [PDF]
Physical Review Letters, 2013 We present the integrated imaging of cold molecules in a microchip environment. The on-chip de- tection is based on REMPI, which is quantum-state-selective and generally applicable. We demon- strate and characterize time-resolved spatial imaging and subsequently use it to analyze the effect of a phase-space manipulation sequence aimed at compressing ...

Optical cycling of AlF molecules
New Journal of Physics, 2021 Aluminium monofluoride (AlF) is a promising candidate for laser cooling and trapping at high densities. We show efficient production of AlF in a bright, pulsed cryogenic buffer gas beam, and demonstrate rapid optical cycling on the Q rotational lines of ...

Linking Ultracold Polar Molecules [PDF]
, 2002 We predict that pairs of polar molecules can be weakly bound together in an ultracold environment, provided that a dc electric field is present. The field that links the molecules together also strongly influences the basic properties of the resulting ...

Cold collisions of complex polyatomic molecules [PDF]
The Journal of Chemical Physics, 2012 We introduce a method for classical trajectory calculations to simulate collisions between atoms and large rigid asymmetric-top molecules. We investigate the formation of molecule-helium complexes in buffer-gas cooling experiments at a temperature of 6.5 K for molecules as large as naphthalene.

High-resolution mid-infrared spectroscopy of buffer-gas-cooled methyltrioxorhenium molecules
New Journal of Physics, 2017 We demonstrate cryogenic buffer-gas cooling of gas-phase methyltrioxorhenium (MTO). This molecule is closely related to chiral organometallic molecules where the parity-violating energy differences between enantiomers is measurable.

Prospects for a narrow line MOT in YO
New Journal of Physics, 2015 In addition to being suitable for laser cooling and trapping in a magneto-optical trap (MOT) using a relatively broad $(\sim 5\;{\rm MHz})$ transition, the molecule YO possesses a narrow-line transition.

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 $10^{-27}\textrm{e.cm}/\sqrt{\textrm{day}}$.

Ultra-cold molecule production. [PDF]
, 2005 The production of Ultra-cold molecules is a goal of many laboratories through out the world. Here we are pursuing a unique technique that utilizes the kinematics of atomic and molecular collisions to achieve the goal of producing substantial numbers of sub Kelvin molecules confined in a trap.
