摘要: We report on the observations of strikingly persistent (lifetimes ~10 s) three-dimensional long-range ordered structures in central 40Ca+ ion component 40Ca+–44Ca+ two-species Coulomb crystals a linear Paul trap. Molecular dynamics simulations strongly indicate that observed are hitherto unpredicted consequence an effective anisotropy inter-particle interaction induced by radio frequency quadrupole-trapping field. The results have implications for such diverse research fields as cold molecular studies and quantum information processing.
