We report the results of a recent measurement of the absolute frequency of the 5s2 S1/2 – 4d2 D5/2 transition of the 88Sr + ion. The optical frequency was...
We describe experiments and measurements on a trapped and laser-cooled single ion of Sr+88 which, when probed on its reference 5sS1/22→4dD5/22 transition at...
The Well-Being of Farm Animals: Challenges and Solutions is the first title in Blackwell Publishing Professional's groundbreaking series Issues in Animal...
Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS), IEEE, octobre 2017
We report a new measurement of the 445 THz electric quadrupole transition of the strontium ion made using a GPS link to the SI second. Compared to our previous...
An atomic frequency reference using a single trapped ion has been evaluated to 1.2×10^-17 uncertainty by exploiting the experimentally observed cancellation of...
2014 IEEE International Frequency Control Symposium proceedings, 2014
We present preliminary results on a method used to determine the differential scalar polarizability Aao of the clock transition of the 88Sr+ ion optical...
2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC), IEEE, juillet 2013
An overview of the key methods used to reduce the uncertainty of the systematic shifts of the strontium ion optical frequency standard is presented. An...
Physical Review A, American Physical Society, 7 février 2013, Volume : 87, Numéro : 2
An ion trap of the end-cap design was built recently at the National Research Council of Canada for improved control of the 88Sr+ single-ion optical frequency...
