Hyperfine and Zeeman interactions in ultracold collisions of molecular hydrogen with atomic lithium
Hubert Jóźwiak, Timur V. Tscherbul, Piotr Wcisło
We present a rigorous quantum scattering study of the effects of hyperfine and Zeeman interactions on cold Li - H collisions in the presence of an external magnetic field usi…
Rovibrational (de-)excitation of H by He revisited
Hubert Jóźwiak, Franck Thibault, Alexandra Viel +2
Collisional (de-)excitation of H by helium plays an important role in the thermal balance and chemistry of various astrophysical environments, making accurate rate coefficien…
Engineering the sensitivity of macroscopic physical systems to variations in the fine-structure constant
Beata Zjawin, Marcin Bober, Roman Ciuryło +3
Experiments aimed at searching for variations in the fine-structure constant are based on spectroscopy of transitions in microscopic bound systems, such as atoms and ions, or r…
Spectral line shape in the limit of frequent velocity-changing collisions
Nikodem Stolarczyk, Piotr Wcisło, Roman Ciurłyo
The speed-dependent spectral line profiles collapse into a simple Lorentz profile in the regime dominated by the velocity-changing collisions. We derive general formulas for the ef…
