Enhancing Divalent Optical Atomic Clocks with the Transition
Matthew A. Bohman, Sergey G. Porsev, David B. Hume +2
Divalent atoms and ions with a singlet ground state and triplet excited state form the basis of many high-precision optical atomic clocks. Along with the metastable $^{3}\m…
Scalable quantum logic spectroscopy
Kaifeng Cui, Jose Valencia, Kevin T. Boyce +2
In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to detect the state of an otherwise inaccessible ion species. This extends precision measurement…
An Al quantum-logic clock with systematic uncertainty below
S. M. Brewer, J. -S. Chen, A. M. Hankin +5
We describe an optical atomic clock based on quantum-logic spectroscopy of the S P transition in Al with a systematic uncertainty of…
Sympathetic ground state cooling and time-dilation shifts in an optical clock
J. -S. Chen, S. M. Brewer, C. W. Chou +3
We report on Raman sideband cooling of to sympathetically cool the secular modes of motion in a - two-ion pair to near th…
A double-well atom trap for fluorescence detection at the Heisenberg limit
Ion Stroescu, David B. Hume, Markus K. Oberthaler
We experimentally demonstrate an atom number detector capable of simultaneous detection of two mesoscopic ensembles with single-atom resolution. Such a sensitivity is a prerequisit…
