Site-selective preparation and multistate readout of molecules in optical tweezers

LRB Picard, GE Patenotte, AJ Park, SF Gebretsadkan… - PRX Quantum, 2024 - APS
Polar molecules are a quantum resource with rich internal structure that can be coherently
controlled. The structure, however, also makes the state preparation and measurement …

Controlling few-body reaction pathways using a Feshbach resonance

S Haze, JL Li, D Dorer, JP D'Incao, PS Julienne… - Nature Physics, 2025 - nature.com
Gaining control over chemical reactions at the quantum level is a central goal of cold and
ultracold chemistry. Here we demonstrate a method for coherently steering the reaction flux …

Dual-species Bose-Einstein condensates of and with tunable interactions

J Chang, S Lee, Y Kim, Y Lim, JW Park - Physical Review Research, 2024 - APS
We report the creation of dual-species Bose-Einstein condensates (BECs) of Na 23 and K
41. Favorable background scattering lengths enable efficient sympathetic cooling of K 41 via …

Quantum theory of molecular orientations: topological classification, complete entanglement, and fault-tolerant encodings

VV Albert, E Kubischta, M Lemeshko, LR Liu - arxiv preprint arxiv …, 2024 - arxiv.org
We formulate a quantum phase space for molecular rotational and nuclear-spin states.
Taking in molecular geometry and nuclear-spin data, we reproduce a molecule's admissible …

Rotational quenching of monofluorides in a cryogenic helium bath

M Londoño, J Péres-Ríos - arxiv preprint arxiv:2502.13046, 2025 - arxiv.org
Buffer gas cooling, one of the most relevant direct cooling techniques for cooling molecules,
relies on dissipating the energy of the molecule via collisions with a buffer gas. The cooling …
