Fluorescence calorimetry of an ion crystal
Marvin Gajewski, Wenbing Li, Sebastian Wolf +5
Motivated by the challenge of identifying intruder ions in a cold ion crystal, we investigate calorimetry from emitted fluorescence light. Under continuous Doppler cooling, the ion…
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…
Stability and dynamics of ion rings in linear multipole traps
Florian Cartarius, Cecilia Cormick, Giovanna Morigi
Trapped singly-charged ions can crystallize as a result of laser cooling. The emerging structure depends on the number of particles and on the geometry of the trapping potential. I…
Phase-dependent light propagation in atomic vapors
S. Kajari-Schroeder, G. Morigi, S. Franke-Arnold +1
Light propagation in an atomic medium whose coupled electronic levels form a diamond-configuration exhibits a critical dependence on the input conditions. In particular, the relati…
Simultaneous cooling of axial vibrational modes in a linear ion-trap
Christof Wunderlich, Giovanna Morigi, Dirk Reiss
In order to use a collection of trapped ions for experiments where a well defined preparation of vibrational states is necessary, all vibrational modes have to be cooled to ensure…
