平面离子晶体本征模的精确实验研究
Precise Experimental Investigation of Eigenmodes in a Planar Ion Crystal
摘要：
二维离子晶体本征模和本征频率的精确表征为将这种结构用于量子模拟的目的提供了基础。本文对二维离子晶体进行了实验和理论研究。我们证明，标准赝势理论准确地预测的离子的位置和不同的晶体配置之间的结构转变的位置。然而，赝势理论是不够的，以确定准确的二维离子晶体的本征频率，但从分辨边带光谱获得的实验数据显示显着的偏差。用Floquet-Lyapunov方法得到的结果与完全含时库仑理论在2.5 × 10 ^（-3）的水平上一致，并从Paul阱中二维离子晶体的动力学中理解了这种效应。这些结果代表了初步的步骤，利用这些结构的量子模拟计划。
英文摘要：
The accurate characterization of eigenmodes and eigenfrequencies of two-dimensional ion crystals provides the foundation for the use of such structures for quantum simulation purposes. We present a combined experimental and theoretical study of two-dimensional ion crystals. We demonstrate that standard pseudopotential theory accurately predicts the positions of the ions and the location of structural transitions between different crystal configurations. However, pseudopotential theory is insufficient to determine eigenfrequencies of the two-dimensional ion crystals accurately but shows significant deviations from the experimental data obtained from resolved sideband spectroscopy. Agreement at the level of 2.5 x 10^(-3) is found with the full time-dependent Coulomb theory using the Floquet-Lyapunov approach and the effect is understood from the dynamics of two-dimensional ion crystals in the Paul trap. The results represent initial steps towards an exploitation of these structures for quantum simulation schemes.
