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…

The Map of Parameter Space in Double Microwave Shielding

Hubert J. Jóźwiak, Ian Stevenson, Sebastian Will +1

Double microwave shielding employs - and -polarized microwave fields, tuned close to the lowest rotational transition, to engineer a long-range repulsive barrier betwee…

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…
