The collisional frequency shift of a trapped-ion optical clock
Amar C. Vutha, Tom Kirchner, Pierre Dubé
Collisions with background gas can perturb the transition frequency of trapped ions in an optical atomic clock. We develop a non-perturbative framework based on a quantum channel d…

Broadband, unpolarized repumping and clearout light sources for Sr single-ion clocks
T. Fordell, T. Lindvall, P. Dubé +3
Future transportable optical clocks require compact and reliable light sources. Here, broadband, unpolarized repumper and state clearout sources for Sr+ single-ion optical clocks a…
