摘要:

离子库仑晶体目前正在成为统计力学介观系统的高度可控的试验台。然而,对这些晶体的动力学进行详细的实验研究仍然是一个实验挑战。在这项工作中,我们展示了如何将多维非线性光谱的概念扩展到离子库仑晶体的动力学研究。我们提出的方案可以实现与国家的最先进的技术,并提供直接访问的动力学,揭示非线性耦合,即使在存在热激发。我们说明了我们的建议,显示如何二维光谱可以用来检测的结构相变的离子晶体,以及模式之间的共振能量交换的签名的优点。此外,我们在这些例子中演示了如何识别不同的退相干机制。

英文摘要:

Ion Coulomb crystals are currently establishing themselves as a highly controllable test-bed for mesoscopic systems of statistical mechanics. The detailed experimental interrogation of the dynamics of these crystals however remains an experimental challenge. In this work, we show how to extend the concepts of multi-dimensional nonlinear spectroscopy to the study of the dynamics of ion Coulomb crystals. The scheme we present can be realized with state-of-the-art technology and gives direct access to the dynamics, revealing nonlinear couplings even in the presence of thermal excitations. We illustrate the advantages of our proposal showing how two-dimensional spectroscopy can be used to detect signatures of a structural phase transition of the ion crystal, as well as resonant energy exchange between modes. Furthermore, we demonstrate in these examples how different decoherence mechanisms can be identified.
