Ultracold chemistry: No longer a disappearing act

Physics Today, 2020
Until now, researchers have struggled to study reactions whose products they couldn’t see.

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.

Quantum weirdness sends ultracold chemistry into overdrive

New Scientist, 2011
Atoms that are normally aloof get cosy at cold temperatures, which could help explain how chemical reactions get started in the cold, diffuse wasteland of interstellar ...

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.

Molecules in electromagnetic fields: from ultracold physics to controlled chemistry

Contemporary Physics, 2020
Molecules that are subjected to external electric and magnetic fields are at first glance much similar to the probably better known case of atoms in such fields, with all the phenomena that have be...

Ultracold chemistry and dipolar collisions in a quantum gas of polar molecules

2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011
Ultracold polar molecular quantum gases promise to open new research directions ranging from the study of ultra-cold chemistry, precision measurements to novel quantum phase transitions. Based on the preparation of high-phase space density gases of polar KRb molecules [1–3], I will discuss the control of dipolar collisions and chemical reactions of ...

Photodissociation and Ultracold Chemistry

2017
We demonstrate a series of experiments involving the photodissociation of ultracold molecules placed in well-defined quantum states with all quantum numbers controlled. We describe how information encoded in the angular distribution of the photofragments can reveal phenomena such as quantum interference and barrier tunneling.

An Introduction to Cold and Ultracold Chemistry

2020
This book provides advanced undergraduate and graduate students with an overview of the fundamentals of cold and ultracold chemistry. Beginning with definitions of what cold and ultracold temperatures mean in chemistry, the book then takes the student through the essentials of scattering theory (classical and quantum mechanical), light-matter ...
