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 ...

Laser spectroscopy of cold molecules [PDF]
Advances in Physics: X, 2016 This paper reviews the recent results in high-resolution spectroscopy on cold molecules. Laser spectroscopy of cold molecules addresses issues of symmetry violation, like in the search for the electric dipole moment of the electron and the studies on energy differences in enantiomers of chiral species; tries to improve the precision to which ...

New Journal of Physics, 2021 We theoretically investigate the laser cooling of fermionic barium monofluoride ( ^137 BaF) molecules, which are promising candidates for precision studies of weak parity violation and nuclear anapole moments.

Toward improved loading, cooling, and trapping of molecules in magneto-optical traps
New Journal of Physics, 2023 Recent experiments have demonstrated direct cooling and trapping of diatomic and triatomic molecules in magneto-optical traps (MOTs). However, even the best molecular MOTs to date still have density 10 ^−5 times smaller than in typical atomic MOTs.

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.

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 ...

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.
