Direct observation of a highly forbidden optical transition in Sm:SrF
Mohit Verma, Luca Talamo, Hiromitsu Sawaoka +1
The intra-configuration transition in Sm:SrF is forbidden for Sm ions in the octahedrally symmetric substitution sites in SrF.…
Electron electric dipole moment searches using clock transitions in ultracold molecules
Mohit Verma, Andrew M. Jayich, Amar C. Vutha
Permanent electric dipole moments (EDMs) of fundamental particles such as the electron are signatures of parity and time-reversal violation due to physics beyond the standard model…
Cold, dense atomic ion clouds produced by cryogenic buffer gas cooling
Nishant Bhatt, Kosuke Kato, Amar C. Vutha
We produce cold and dense clouds of atomic ions (Ca, Dy) by laser ablation of metal targets and cryogenic buffer gas cooling of the resulting plasma. We measure the tempera…
Improved estimate of the collisional frequency shift in Al optical clocks
Jack Davis, Pierre Dubé, Amar C. Vutha
Collisions between background gas particles and the trapped ion in an atomic clock can subtly shift the frequency of the clock transition. The uncertainty in the correction for thi…
