B01 – Collective quantum dynamics of structural- and spin-defects in ion crystals
Summary
We characterize defect structures in trapped ion crystals in a common experiment and theory approach. For this purpose, the experimental group will setup a versatile ion trap and work with mixed-species linear crystals composed of up to 50 ions using the atomic ions 40Ca+ and 9Be+. The theory will characterize the dynamics of this system for experimentally-relevant configurations. Our aim is to control and tailor the defects’ cooperative properties which are mediated by the vibrations of the embedding crystal. In turn, we aim at controlling the dynamics of this spin boson system using mass-defects and spin-dependent forces.
