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…
Tunable state-dependent interactions in collisionally stable mixtures of polar molecules
Hubert J. Jóźwiak, Hanwei Yang, Eugen Dizer +2
We propose encoding a pseudo-spin- system in the ground () and first excited () vibrational states of polar molecules. Double microwave shielding simultaneously shie…
Ro-vibrational van der Waals interaction between ultracold polar molecules
Kang Feng, Hanwei Yang, Hubert J. Jóźwiak +1
We describe the ro-vibrational van der Waals interaction between ultracold polar molecules. This interaction is strong, leading to fast elastic collisions and orders of magnitude s…
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…
Mapping the parameter space of double microwave shielding
Hubert J. Jóźwiak, Hubert J. Jóźwiak, Ian Stevenson +2
Double microwave shielding employs - and -polarized microwave fields, tuned close to the lowest rotational transition, to engineer a long-range repulsive barrier between…
Low-Energy Purification of Crystal Defects by Rydberg Excitons
Shiva Kant Tiwari, Tijs Karman, Valentin Walther
Recent experiments show that optically generated Rydberg excitons in cuprous oxide can neutralize charged impurities, strongly reducing stray electric fields and effectively purify…
