# Heat transport through ion crystals

@article{Freitas2013HeatTT, title={Heat transport through ion crystals}, author={Nahuel Freitas and Esteban A. Martinez and Juan Pablo Paz}, journal={Physica Scripta}, year={2013}, volume={91} }

We study the thermodynamical properties of crystals of trapped ions which are laser cooled to two different temperatures in two separate regions. We show that these properties strongly depend on the structure of the ion crystal. Such structure can be changed by varying the trap parameters and undergoes a series of phase transitions from linear to zig-zag or helicoidal configurations. Thus, we show that these systems are ideal candidates to observe and control the transition from anomalous to…
