Preparation of Translationally Cold Neutral Molecules

open access: yesCHIMIA, 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]

open access: yesAdvances 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 ...

Cold and ultracold molecules in the twenties [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
A diversity of experimental techniques has been developed over the last 25 years to create samples of molecular gases at temperatures close to the Absolute Zero—here we consider samples in the range from 10s of Kelvin (cold) down to 10s of nanoKelvin ...

Preparation of an ultra-cold sample of ammonia molecules for precision measurements [PDF]

open access: yesJournal of Molecular Spectroscopy, 2014
We present experiments in which an ultra-cold sample of ammonia molecules is released from an electrostatic trap and recaptured after a variable time.

Organic Molecules from Biochar Leacheates Have a Positive Effect on Rice Seedling Cold Tolerance

open access: yesFrontiers in Plant Science, 2017
Biochar is known to have a number of positive effects on plant ecophysiology. However, limited research has been carried out to date on the effects and mechanisms of biochar on plant ecophysiology under abiotic stresses, especially responses to cold.

Testing the time-invariance of fundamental constants using cold, and not so cold, molecules

open access: yes, 2010
I will discuss the status of two experiments ultimately aimed at testing the time-invariance of the proton-to-electron mass using a thermal beam of CO molecules and using cold ammonia molecules in a fountain.

A laser cooling scheme for precision measurements using fermionic barium monofluoride (137Ba19F) molecules

open access: yesNew 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

open access: yesNew 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.

Optical cycling of AlF molecules

open access: yesNew 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 ...
