      abstract     = {We report on the sympathetic cooling and Coulomb
                      crystallization of xenon highly charged ions (HCIs) with
                      laser-cooled Ca+ ions. The HCIs are produced in a compact
                      electron beam ion trap, then charge selected, decelerated,
                      and finally injected into a cryogenic linear Paul trap.
                      There, they are captured into 40Ca+ Coulomb crystals, and
                      co-crystallized within them, causing dark voids in their
                      fluorescence images. Fine control over the number of trapped
                      ions and HCIs allows us to realize mixed-species crystals
                      with arbitrary ordering patterns. By investigating Xeq+--Ca+
                      strings, we confirm the HCI charge states, measure their
                      lifetime and characterize the mixed-species motional modes.
                      Our system effectively combines the established quantum
                      control toolbox for Ca+ with the rich set of atomic
                      properties of Xe highly charged ions, providing a
                      resourceful platform for optical frequency metrology,
                      searches for signatures of new physics, and quantum
                      information science.},
