Quantum entanglement has been generated and verified in cold-atom experiments and
used to make atom-interferometric measurements below the shot-noise limit. However …

Tightly focused laser beams form optical tweezers that can hold and manipulate individual
atoms. They give superb control over microscopic quantum systems and have paved the …

We measure inelastic collisions between ultracold CaF molecules by combining two optical
tweezers, each containing a single molecule. We observe collisions between Σ 2 CaF …

We report the preparation of exactly one 87 Rb atom and one 133 Cs atom in the same
optical tweezer as the essential first step towards the construction of a tweezer array of …

Quantum coherent control of collisions beyond the ultracold regime can face a major
challenge due to the incoherent addition of different partial-wave contributions to the total …

The multichannel Na-Cs interactions are characterized by a series of measurements using
two atoms in an optical tweezer, along with a multichannel quantum defect theory (MQDT) …

Laguerre–Gaussian (LG) beams have orbital angular momentum (OAM). A particle trapped
in an LG beam will rotate about the beam axis, due to the transfer of OAM. The rotation of the …

The introduction of optical tweezers for trapping atoms has opened remarkable opportunities
for manipulating few-body systems. Here, we present the first bottom-up assembly of atom …

We investigate the photoassociation dynamics of exactly two laser-cooled Rb 85 atoms in an
optical tweezer and reveal fundamentally different behavior to photoassociation in many …

The optical theorem is a fundamental aspect of quantum scattering theory. Here, we
generalize this theorem to the case where the incident scattering state is a superposition of …
