Preparation of Translationally Cold Neutral Molecules
CHIMIA, 2011 Efforts at EPFL to obtain translationally cold neutral molecules are described. Active deceleration of polar molecules is performed by confining the molecules in moving three-dimensional electrostatic traps, and by appropriately choosing the ...

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 ...

Cold SO2 molecules by Stark deceleration [PDF]
The European Physical Journal D, 2008 We produce SO_2 molecules with a centre of mass velocity near zero using a Stark decelerator. Since the initial kinetic energy of the supersonic SO_2 molecular beam is high, and the removed kinetic energy per stage is small, 326 deceleration stages are necessary to bring SO_2 to a complete standstill, significantly more than in other experiments.

Physica Scripta, 2004 In this paper we overview recent results on the formation of translationally cold molecules. While there are some methods relying on direct cooling of molecules, we shall concentrate on the photoassociation technique that starts from laser-cooled atoms.

Characterizing the Zeeman slowing force for 40Ca19F molecules
New Journal of Physics, 2021 In this paper we investigate the feasibility of Zeeman slowing calcium monofluoride molecules originating from a cryogenic buffer gas cell. We measure the ${A}^{2}{{\Pi}}_{1/2}(v=0,J=\frac{1}{2})-{X}^{2}{{\Sigma}}_{1/2}(v=0,N=1)$ hyperfine spectrum of ...

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.

Enhanced molecular yield from a cryogenic buffer gas beam source via excited state chemistry
New Journal of Physics, 2020 We use narrow-band laser excitation of Yb atoms to substantially enhance the brightness of a cold beam of YbOH, a polyatomic molecule with high sensitivity to physics beyond the standard model (BSM).

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.

Low-energy collisions between carbon atoms and oxygen molecules in a magnetic trap
New Journal of Physics, 2020 Trapping of atoms and molecules in electrostatic, magnetic and optical traps has enabled studying atomic and molecular interactions on a timescale of many seconds, allowing observations of ultra-cold collisions and reactions.
