Measurement of the variation of electron-to-proton mass ratio using ultracold molecules produced from laser-cooled atoms [PDF]
Nature Communications, 2019 Ultracold molecules are suitable platforms for precision measurements due to their internal degrees of freedom. Here the authors derive a limit on the variation of the electron-to-proton mass ratio by using the spectroscopy of ultracold KRb molecules.

Two- and many-body physics of ultracold molecules dressed by dual microwave fields [PDF]
Nature CommunicationsWe investigate the two- and many-body physics of ultracold polar molecules dressed by dual microwaves with distinct polarizations. Using Floquet theory and multichannel scattering calculations, we identify a regime with the largest elastic-to-inelastic ...

Towards Ultracold Chiral Molecules
CHIMIA, 2018 Atoms can be cooled and trapped efficiently with the help of lasers. So-called Doppler cooling takes advantage of momentum transfer upon absorption and emission of photons and of Doppler shifts to facilitate effectively closed optical absorption–
