Manipulating the structure of ion Coulomb crystals with light
Abstract
Coulomb crystallisation of laser-cooled ensembles of ions in harmonic traps has been studied experimentally with many spectacular results in recent years [1-3]. It is well known that for sufficiently large numbers of ions the ground state of a Coulomb crystal in such a system has a body-centred cubic (bcc) structure. However, in experiments with crystals of up to a few 10<sup>4</sup> ions, structural transitions between bcc and, for example, facecentred cubic (fcc) or hexagonal close packed (hcp) structures are observed [4]. For constant ion densities, the lattice spacing of the planes of highest density differs only by about 3% between bcc and fcc structures and simulations predict very small energy differences, thus thermal effects even at temperatures in the mK regime are sufficient to excite these transitions. Here we study numerically the possibility of controlling and switching the crystal structure with the help of periodic potentials generated by the dipole forces of standing-wave light fields.
