Deterministic loading of molecular arrays by microwave-assisted collisions
Etienne F. Walraven, Kang Feng, Jonas Rodewald +2
Molecular tweezer arrays offer great prospects for quantum simulation, sensing, and computing, and would benefit from methods that enhance loading efficiency. Whereas light-assiste…
Evolution of dipole-dipole dynamics in cold ammonia collisions
Yao Chang, André J. A. van Roij, Stach E. J. Kuijpers +4
Cold polar molecules offer fascinating prospects for ultracold chemistry and quantum physics, including new platforms for quantum simulation or computation. However, their inherent…
Hyperfine van der Waals repulsion between open-shell polar molecules
Etienne F. Walraven, Tijs Karman
We describe a novel type of interaction between open-shell polar molecules at sub-millikelvin temperatures. This hyperfine van der Waals interaction occurs between two molecules in…
Scheme for Deterministic Loading of Laser-Cooled Molecules into Optical Tweezers
Etienne F. Walraven, Michael R. Tarbutt, Tijs Karman
We propose to repeatedly load laser-cooled molecules into optical tweezers, and transfer them to storage states that are rotationally excited by two additional quanta. Collisional…
Rotational-state dependence of interactions between polar molecules
Etienne F. Walraven, Tijs Karman
The long-range electrostatic interactions between molecules depend strongly on their relative orientation, which manifests as a rotational state dependence. Interactions between mo…
