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].
