Collisional losses of ultracold molecules due to intermediate complex formation
Krzysztof Jachymski, Marcin Gronowski, Michał Tomza
Abstract
The authors study the structure of four-atom complexes which can be formed in collisions of ultracold molecules, demonstrating that couplings between internal states can be large enough to increase their lifetime beyond semiclassical estimates. They consider the interplay between the complex lifetime, photon absorption rate from the trapping laser, and secondary inelastic collisions with the remaining molecules and show that it can lead to vastly different scenarios of the loss dynamics.
