Domain formation and structural stabilities in mixed-species Coulomb crystals induced by sympathetically cooled highly charged ions
L. -A. Rüffert, E. A. Dijck, L. Timm +2
There is a growing interest in high-precision spectroscopy and frequency metrology for fundamental studies using sympathetically cooled highly charged ions (HCIs) embedded in Coulo…
Non-Abelian vibron dynamics in trapped-ion arrays
L. Timm, H. Weimer, L. Santos
Trapped-ion arrays offer interesting possibilities for quantum simulation. We show that a proper arrangement of elliptical micro-traps combined with the external driving of the mic…
Heat transport in a Coulomb ion crystal with a topological defect
L. Timm, H. Weimer, L. Santos +1
The thermodynamics of low-dimensional systems departs significantly from phenomenologically deducted macroscopic laws. Particular examples, not yet fully understood, are provided b…
Quantum nanofriction in trapped ion chains with a topological defect
L. Timm, L. A. Rüffert, H. Weimer +2
Trapped ion systems constitute a well controllable scenario for the study and emulation of nanofriction, and in particular of Frenkel-Kontorova-like models. This is in particular t…
Finite temperature spectrum at the symmetry-breaking linear-zigzag transition
Jan Kiethe, Lars Timm, Haggai Landa +3
We investigate the normal mode spectrum of a trapped ion chain at the symmetry-breaking linear to zigzag transition and at finite temperatures. For this purpose we modulate the amp…
Energy localization in interacting atomic chains with topological solitons
L. Timm, H. Weimer, L. Santos +1
Topological defects in low-dimensional non-linear systems feature a sliding-to-pinning transition of relevance for a variety of research fields, ranging from biophysics to nano- an…
