Experimental determination of the nuclear magnetic octupole moment of Ba ion
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We perform precision measurements on the 5D manifold hyperfine intervals of a single trapped ion, Ba. RF spectroscopy is used to measure the hyperfine intervals…
Sub-Doppler Cavity Cooling Beyond The Lamb-Dicke Limit
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We investigate the dynamics of cavity cooling of a single ion beyond the Lamb-Dicke regime and demonstrate a cooling limit of approximately 50% of the Doppler temperature using a h…
Minimization of Ion Micromotion in a Linear Paul Trap with a High Finesse Cavity
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We demonstrate minimization of ion micromotion in a linear Paul trap with the use of a high finesse cavity. The excess ion micromotion projected along the optical cavity axis or al…
Spectroscopy on a single trapped 137Ba+ ion for nuclear magnetic octupole moment determination
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We present precision measurements of the hyperfine intervals in the 5D3/2 manifold of a single trapped Barium ion, 137 Ba+ . Measurements of the hyperfine intervals are made betwee…
State detection using coherent Raman repumping and two-color Raman transfers
Boon Leng Chuah, Nick C. Lewty, Murray D. Barrett
We demonstrate state detection based on coherent Raman repumping and a two-color Raman state transfer. The Raman coupling during detection selectively eliminates unwanted dark stat…
