Ultracold field-linked tetratomic molecules [PDF]
Nature, 2023 Abstract Ultracold polyatomic molecules offer intriguing new opportunities [1] in cold chemistry [2, 3], precision measurements [4], and quantum information processing [5, 6], thanks to their rich internal structure. However, their increased complexity compared to diatomic molecules presents a formidable challenge to employ conventional cooling

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.

Collisional cooling of ultracold molecules [PDF]
Nature, 2020 Since the original work on Bose-Einstein condensation, quantum degenerate gases of atoms have allowed the quantum emulation of important systems from condensed matter and nuclear physics, as well as the study of novel many-body states with no analog in other fields of physics.

Ultracold polar molecules as qudits
New Journal of Physics, 2020 We discuss how the internal structure of ultracold molecules, trapped in the motional ground state of optical tweezers, can be used to implement qudits. We explore the rotational, fine and hyperfine structure of ^40 Ca ^19 F and ^87 Rb ^133 Cs, which are

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–

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 ...

Ultracold molecules and ultracold chemistry
Molecular Physics, 2009 The recent development of a range of new methods for producing samples of gas phase molecules that are translationally cold (T < 1 K) or ultracold (T < 1 mK) is driving efforts to study reactive and inelastic collisional processes in these temperature regimes. In this review article the new methods for cold/ultracold molecule production are reviewed in
