Chemistry at ultracold temperatures

Chemical Physics Letters, 2001
Abstract The reaction F+H 2 →FH+H is studied quantum mechanically at ultralow temperatures. The low temperature limit of its rate coefficient is controlled by the attractive van der Waals interaction and quantum mechanical threshold effects. When the fine-structure splitting of the fluorine atom is neglected, the rate coefficient passes through a ...

Manipulation of Ultracold Chemistry

Frontiers in Optics 2010/Laser Science XXVI, 2010
I will discuss the molecular physics underlying recent experimental observations of, and control over, chemical reactions at JILA. For these polar species, possible handles for control include the quantum statistics of the molecules, the temperature, applied electric fields, and confinement in reduced-dimensional geometry.

Towards ultracold chemistry; manipulation of polar molecules with electric fields

International Quantum Electronics Conference, 2005., 2005
Deceleration and trapping of polar molecules using time-varying electric fields is described. Decelerated ND3 and OH molecules are trapped in an electrostatic trap, slow beams of ammonia are injected in a storage ring and have also been used for testing micro-structured optical elements and for high-resolution spectroscopy.

State-to-state chemistry for three-body recombination in an ultracold rubidium gas

Science, 2017
Tracking a trio of rubidium atoms Crossed molecular beams have provided decades' worth of knowledge into how quantum mechanics governs chemical reactivity. Nonetheless, the technique is generally limited to the collision of two partners. Wolf et al.
