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 …

Ultracold coherent control of molecular collisions at a Förster resonance

T Delarue, G Quéméner - Physical Review A, 2024 - APS
We show that the precise microwave preparation of a quantum superposition between three
rotational states of an ultracold dipolar molecule generates controllable interferences in their …
