Lu clock comparison at the level via correlation spectroscopy
Zhang Zhiqiang, Kyle J. Arnold, Rattakorn Kaewuam +1
We experimentally demonstrate agreement between two Lu frequency references using correlation spectroscopy. From a comparison at different magnetic fields, we obtain a…
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…
Oscillating quadrupole effects in high precision metrology
Kyle J. Arnold, R. Kaewuan, T. R. Tan +1
The influence of oscillating quadrupole fields on atomic energy levels is examined theoretically and general expressions for the quadrupole matrix elements are given. The results a…
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…
Non-equilibrium phase transition in a spin-1 Dicke model
Zhang Zhiqiang, Chern Hui Lee, Ravi Kumar +4
We realize a spin-1 Dicke model using magnetic sub-levels of the lowest F=1 hyperfine level of Rb atoms confined to a high finesse cavity. We study this system under conditi…
Suppression of clock shifts at field-insensitive transitions
Kyle J. Arnold, M. D. Barrett
We show that it is possible to significantly reduce quadrupole and tensor polarizability shifts of a clock transition by operating at a judiciously chosen field-insensitive point.…
