论文摘要
我们通过将离子的各种内部和外部耦合术语与哈密顿陷阱中的各种内部和外部耦合术语结合到哈密顿式的陷阱中,计算了保罗陷阱中单个ca $^+$ ion的rydberg光谱。耦合术语包括Ca $^+$中的自旋轨道耦合,电荷(电子和离子核)耦合到射频和静态场,Paul Trap中的离子电子耦合以及离子质量中心耦合。电子rydberg状态由E $^ - $+Ca $^{2+} $的单电子模型的潜力精确描述,并且获得了许多激发rydberg状态的精确特征力,量子缺陷参数以及静态和张量极化。时间周期性的RF哈密顿量在浮雕的基础上进行了扩展,并且将诱捕的野外Rydberg线与最近观察到的Ca $^+(23p)$和Ca $^+(52f)$ Rydberg Lines进行了比较。
We compute the Rydberg spectrum of a single Ca$^+$ ion in a Paul trap by incorporating various internal and external coupling terms of the ion to the trap in the Hamiltonian. The coupling terms include spin-orbit coupling in Ca$^+$, charge (electron and ionic core) coupling to the radio frequency and static fields, ion-electron coupling in the Paul trap, and ion center-of-mass coupling. The electronic Rydberg states are precisely described by a one-electron model potential for e$^-$+Ca$^{2+}$, and accurate eigenenergies, quantum defect parameters, and static and tensor polarizabilities for a number of excited Rydberg states are obtained. The time-periodic rf Hamiltonian is expanded in the Floquet basis, and the trapping-field-broadened Rydberg lines are compared with recent observations of Ca$^+(23P)$ and Ca$^+(52F)$ Rydberg lines.
