Quantum Dynamics of Astrophysically Important Molecules

Project goals

The project is dedicated to the theoretical investigation and modelling of atomic collisions and dynamics with the aim of determining the scattering characteristics that will enable us to study the cosmological variability of the proton-to-electron mass ratio for systems such as OH and CH radicals and other dimers (e.g. KCl). Another aim of the project is to predict high-precision spectral properties of helium and lithium like atoms with the inclusion of quantum electrodynamical corrections.

  • Annotation in Czech

    Projekt je zaměřen na teoretické zkoumání a modelování atomových srážek a jejich dynamiky s cílem určit rozptylové charakteristiky umožňující studovat časoprostorovou variabilitu poměru mezi hmotou protonu a elektronu. V úvahu připadají systémy jako OH a CH radikály a jiné dimery (např. KCl). Dalším cílem projektu je předpovědět vysoce přesná spektra heliu a lithiu podobných atomů se zahrnutím kvantově elektrodynamických korekcí.
