13 p, 194.7 KB Dynamics of an ion chain in a harmonic potential / Morigi, Giovanna (University of Ulm. Department of Quantum Physics) ; Fishman, Shmuel (Technion. Department of Physics (Haifa, Israel))
Cold ions in anisotropic harmonic potentials can form ion chains of various sizes. Here, the density of ions is not uniform, and thus the eigenmodes are not phononic-like waves. We study chains of N 1 ions and evaluate analytically the long-wavelength modes and the density of states in the short-wavelength limit. [...]
