Structural and dynamical properties of quasi-1D dipolar crystals — •Florian Cartarius1,2, Anna Minguzzi1, and Giovanna Morigi2 — 1Université de Grenoble 1/CNRS, LPMMC UMR 5493, B.P. 166, 38042 Grenoble, France — 2Theoretische Physik, Universität des Saarlandes, 66123 Saarbrücken, Germany
We study the ground state of classical dipolar particles in quasi-1D geometries, which can be realized in highly anisotropic traps. Here, the dipolar interaction between the particles can be made repulsive by confining the particles on a plane in presence of an external field perpendicular to it. We study the equilibrium configurations which are obtained for decreasing values of the trap aspect ratio by means of a Basin-Hopping Monte Carlo method and of analytical calculations of the motional spectra, and determine the structural phase diagram.
