The last few years have seen rapid progress in the application of laser cooling to molecules.
In this review, we examine what kinds of molecules can be laser cooled, how to design a …

Precision measurements in molecules have advanced rapidly in recent years through
developments in techniques to cool, trap, and control. The complexity of molecules makes …

We present a practical roadmap to achieve optical cycling and laser cooling of asymmetric
top molecules (ATMs). Our theoretical analysis describes how reduced molecular symmetry …

Dipole spin-wave states of atomic ensembles with wave vector k (ω) mismatched from the
dispersion relation of light are difficult to access by far-field excitation but may support rich …

We demonstrate buffer-gas cooling, high-resolution spectroscopy, and cycling fluorescence
of cold barium monofluoride (BaF) molecules. Our source produces an intense and …

Optical cycling transitions and direct laser cooling have recently been demonstrated for a
number of alkaline-earth dimers and trimer molecules. This is made possible by diagonal …

Optical control of polyatomic molecules promises new opportunities in precision metrology
and fundamental chemistry, as well as quantum information and many-body science …

Advances of quantum control technology have led to nearly perfect single-qubit control of
nuclear spins and atomic hyperfine ground states. In contrast, quantum control of strong …

Recent theoretical investigations have indicated that rapid optical cycling should be feasible
in complex polyatomic molecules with diverse constituents, geometries, and symmetries …

Atoms are ideal quantum sensors and quantum light emitters. Interfacing atoms with
nanophotonic devices promises nanoscale sensing and quantum optical functionalities. But …
