Theme 1 colloquium: "Cold chemistry: on the role of internal degrees of freedom" (Lecture)

Monday 4 December 2017Add to my calendar
from 16:00

Jesús Pérez Ríos dec2017Cold chemistry is the study of chemical reactions at T ≲1K, where only a few partial waves will contribute to the scattering process, thus offering the possibility of revealing the intrinsic quantal nature of the underlying intermolecular interactions, otherwise obscured in room temperature experiments. In particular, the field is mainly devoted to the study of molecular ion-neutral collisions at T~1mK since the presence of internal degrees of freedom opens up new avenues of research such as state selective chemistry, sympathetic cooling of molecular ions and quantum logic spectroscopy, among others. These lines of research rely upon a deep understanding of the available energetic exchange mechanisms regarding different degrees of freedom of the molecular ion and its colliding partner. In this talk we will present a theoretical framework for the study of rotational and vibrational relaxation phenomena in cold molecular ions as well as for different chemical processes such as three-body recombination. In particular, we will focus on a certain process important to a number of experiments.
