Excitation and Transport of Discrete Solitons in Coulomb Crystals — •Jonathan Brox1, Philip Kiefer1, Miriam Bujak1, Haggai Landa2, and Tobias Schaetz1 — 1Atom-, Molekül- und optische Physik, Physikalisches Institut, Universität Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg — 2LPTMS, Université Paris Sud, Orsay, France
We study structural defects (kinks), which are formed in 2D Coulomb crystal [1].
Ion crystals with such structural defects feature localized modes in the vibrational spectrum[2]. We show that resonant excitation of kinks leads to a directed transport conditional on the conformation of the topological protected defect inside the ion crystal [3].
