Doppler and collisional frequency shifts in trapped-atom clocks
Amar Vutha, Tom Kirchner, Pierre Dubé
Collisions with background gas particles can shift the resonance frequencies of atoms in atomic clocks. The internal quantum states of atoms can also become entangled with their mo…

A screened independent atom model for the description of ion collisions from atomic and molecular clusters
Hans Jürgen Lüdde, Marko Horbatsch, Tom Kirchner
We apply a recently introduced model for an independent-atom-like calculation of ion-impact electron transfer and ionization cross sections to proton collisions from water, neon, a…
