Ion Coulomb crystals in scalable ion traps for precision spectroscopy — •Jan Kiethe, Dimitri Kalincev, Jonas Keller, Tobias Burgermeister, and Tanja E. Mehlstäubler — Physikalisch-Technische Bundesanstalt, Braunschweig, Germany

We report on progress towards a multi-ion clock based on In+/Yb+ ion Coulomb crystals, stored in a segmented linear Paul trap. In our currently operational prototype trap we characterized systematic shifts due to micromotion[1] and excess heating rates at the level of fractional frequency shifts of 10−19 and below. A heating rate of 1.4 phonons per second at 500 kHz was observed.

A next generation ion trap based on aluminum nitride ceramics, was tested at the CMI in Prague. The warming of the trap was measured to be 2 K at operational conditions, in agreement with simulations[2].

The well-controlled Coulomb crystals in our setup are also used to study many-body physics of strongly interacting systems. In particular, we investigate the dynamics of solitons in two-dimensional ion Coulomb crystals.
