Hyperfine averaging by dynamic decoupling in a multi-ion lutetium clock
R. Kaewuam, T. R. Tan, K. J. Arnold +3
We propose and experimentally demonstrate a scheme which effects hyperfine averaging during a Ramsey interrogation of a clock transition. The method eliminates the need to average…
Dicke model simulation via cavity-assisted Raman transitions
Zhang Zhiqiang, Chern Hui Lee, Ravi Kumar +5
The Dicke model is of fundamental importance in quantum mechanics for understanding the collective behaviour of atoms coupled to a single electromagnetic mode. In this paper, we de…
Developing a field independent frequency reference by averaging over transitions to multiple hyperfine levels
M. D. Barrett
We show that by averaging over transitions to multiple hyperfine levels, quadrupole shifts and dominant Zeeman effects exactly cancel whenever the nuclear spin, I, is at least as l…
Realization of the Dicke model using cavity-assisted Raman transitions
Markus P. Baden, Kyle J. Arnold, Arne L. Grimsmo +2
We realize an open version of the Dicke model by coupling two hyperfine ground states using two cavity-assisted Raman transitions. The interaction due to only one of the couplings…
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…
Micromotion in trapped atom-ion systems
Le Huy Nguyen, Amir Kalev, Murray D. Barrett +1
We examine the validity of the harmonic approximation, where the radio-frequency ion trap is treated as a harmonic trap, in the problem regarding the controlled collision of a trap…
