“…On the other hand, precision measurements with ions stored in a non-ideal trap, the anharmonic components of the potential Φ (k>2) (x, y, z) are non-negligible due to the fact that they change ion dynamics and also affect the systematics. For minimizing such effects several groups, such as, NPL UK [41], NRC Canada [11] and PTB Germany [42,43] have come up with different end cap trap designs for establishing single ion frequency standards. Here we aim to identify a new end cap trap geometry in which the trap induced quadrupole shift can be minimized.…”

We propose a new ion-trap geometry to carry out accurate measurements of the quadrupole shifts in the 171 Yb-ion. This trap will produce nearly ideal harmonic potential where the quadrupole shifts due to the anharmonic components can be reduced by four orders of magnitude. This will be useful to reduce the uncertainties in the clock frequency measurements of the 6s 2 S 1/2 → 4f 13 6s 2 2 F 7/2 and 6s 2 S 1/2 → 5d 2 D 3/2 transitions, from which we can deduce precise values of the quadrupole moments (Θs) of the 4f 13 6s 2 2 F 7/2 and 5d 2 D 3/2 states. Moreover, it may be able to affirm validity of the measured Θ value of the 4f 13 6s 2 2 F 7/2 state where three independent theoretical studies defer almost by one order in magnitude from the measurement. We also perform calculations of Θs using the relativistic coupled-cluster (RCC) method. We use these Θ values to estimate quadrupole shift that can be measured in our proposed ion trap experiment.

“…Increased levels of performance have allowed tests of fundamental physics [1] and new avenues of exploration in quantum many body physics [2,3]. Increasing levels of accuracy and stability continue to be made with atomic clocks based on optical transitions in isolated atoms [4][5][6][7][8][9][10][11][12]. By now a number of groups have demonstrated superior performance over the current caesium frequency standards with the best clocks to date having inaccuracy at the 10 −18 level [4,5,13].…”

Singly ionised Lutetium has recently been suggested as a potential clock candidate. Here we report a joint experimental and theoretical investigation of Lu + . Measurements relevant to practical clock operation are made and compared to atomic structure calculations. Calculations of scalar and tensor polarizabilities for clock states over a range of wavelengths are also given. These results will be useful for future work with this clock candidate.

Prospects for atomic clocks based on large ion crystals

We investigate the feasibility of precision frequency metrology with large ion crystals. For clock candidates with a negative differential static polarisability, we show that micromotion effects should not impede the performance of the clock. Using Lu + as a specific example, we show that quadrupole shifts due to the electric fields from neighbouring ions do not significantly affect clock performance. We also show that effects from the tensor polarisability can be effectively managed with a compensation laser at least for a small number of ions ( 10 3 ). These results provide new possibilities for ion-based atomic clocks, allowing them to achieve stability levels comparable to neutral atoms in optical lattices and a viable path to greater levels of accuracy.
