Recently, a research team led by Prof. Pan Jianwei and Prof. Zhao Bo
from the University of Science and Technology of China (USTC) of the
Chinese Academy of Sciences (CAS), used adiabatic magneto-association to
create an ultracold gas of triatomic molecules with high phase-space
density from a degenerate mixture of 23Na40K molecules and 40K atoms for the first time. This work was published in Science.

The use of highly controllable ultracold
molecules in the simulation of complex chemical reactions allows for
comprehensive study of complex systems. Direct cooling of ultracold
molecules is challenging due to the complexity of the vibrational and
rotational energy levels in molecules.

A method has been proposed for coherently converting ultracold atoms
into ultracold molecules. Diatomic molecules, which benefit from high
phase-space density and low temperature and can be coherently
transferred to the ground state using a laser, have been created using the Feshbach resonance.
