Ultracold molecules confined in optical lattices or tweezer traps can be used to process
quantum information and simulate the behaviour of many-body quantum systems. Molecules …

In recent years, an increasingly large variety of molecular species have been successfully
cooled to low energies, and innovative techniques continue to emerge to reach ever more …

Ultracold atoms, molecules and ions provide a unique playground to explore chemistry at
ultracold temperatures. In this Review, we discuss what makes these systems particularly …

Ultracold polar molecules possess long-range, anisotropic and tunable dipolar interactions,
providing opportunities to probe quantum phenomena that are inaccessible with existing …

Collisional resonances are important tools that have been used to modify interactions in
ultracold gases, for realizing previously unknown Hamiltonians in quantum simulations, for …

Chemical reactions, in which bonds break and form, are highly dynamic quantum processes.
A fundamental question is whether coherence can be preserved in chemical reactions and …

We report on the creation of bosonic NaCs molecules in their absolute rovibrational ground
state via stimulated Raman adiabatic passage. We create ultracold gases with up to 22 000 …

Collisional complexes, which are formed as intermediate states in molecular collisions, are
typically short-lived and decay within picoseconds. However, in ultracold collisions involving …

In recent years, there has been notable progress in the preparation and control of ultracold
gases of diatomic molecules. The next experimental challenge is the production of ultracold …

Quantum states with long-lived coherence are essential for quantum computation,
simulation and metrology. The nuclear spin states of ultracold molecules prepared in the …
