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

Laser cooling and trapping of atoms and atomic ions has led to advances including the
observation of exotic phases of matter,, the development of precision sensors and state-of …

Recent advances have enabled studies of atom–ion chemistry at unprecedentedly low
temperatures, allowing precision observation of chemical reactions and novel chemical …

We report the laser cooling of a single Ca 40+ ion in a Penning trap to the motional ground
state in one dimension. Cooling is performed in the strong binding limit on the 729-nm …

Cold molecular ions are promising candidates in various fields ranging from precision
spectroscopy and test of fundamental physics to ultracold chemistry. Control of internal and …

Polyatomic molecular ions contain many desirable attributes of a useful quantum system,
including rich internal degrees of freedom and highly controllable coupling to the …

Scaling up from prototype systems to dense arrays of ions on chip, or vast networks of ions
connected by photonic channels, will require developing entirely new technologies that …

We use recently developed angulon theory [R. Schmidt and M. Lemeshko, Phys. Rev. Lett.
114, 203001 (2015) PRLTAO 0031-9007 10.1103/PhysRevLett. 114.203001] to study the …

We investigated helium-mediated translational and rotational thermalization of the aluminum
monofluoride (AlF) molecule at cryogenic temperatures via an ab initio potential energy …

Internal states of polar molecules can be controlled by microwave-frequency electric dipole
transitions. If the applied microwave electric field has a spatial gradient, these transitions …
