The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally …

The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …

The ExoMol database (www. exomol. com) provides extensive line lists of molecular
transitions which are valid over extended temperature ranges. The status of the current …

We experimentally study the full counting statistics of few-body Rydberg aggregates excited
from a quasi-one-dimensional atomic gas. We measure asymmetric excitation spectra and …

We show how to use polar molecules in an optical lattice to engineer quantum spin models
with arbitrary spin S≥ 1/2 and with interactions featuring a direction-dependent spin …

Calcium monofluoride (CaF) is magnetically slowed and trapped using optical pumping.
Starting from a collisionally cooled slow beam, CaF with an initial velocity of∼ 30 m/s is …

The dynamics of a cloud of ultracold two-level atoms is studied at off-resonant laser driving
to a Rydberg state. We find that resonant excitation channels lead to strongly peaked spatial …

We show that ultracold polar molecules pinned in an optical lattice can be used to access a
variety of exotic spin models, including the Kitaev honeycomb model. Treating each …

Competing short-and long-range interactions represent distinguished ingredients for the
formation of complex quantum many-body phases. Their study is hard to realize with …

A correspondence is established between the electric dipole matrix elements of a
polyatomic symmetric top molecule in a state with nonzero projection of the total angular …
