AI 中文摘要
传统用于囚禁离子冷却和门操作的激光控制方案局限于弱激光强度和小Lamb-Dicke参数范围。为克服此限制，我们提出暗极化子概念：与拉姆达激光配置完全解耦的赝自旋极化空间扩展态。在此框架下，所有高阶Lamb-Dicke项合并为一个与激光强度无关的线性耦合。我们用它明确解释了近期高强度激光电磁诱导透明实验实现中冷却速率受限的原因。
英文摘要
Conventional laser control schemes for cooling and gate operation of trapped ions are limited to the regime of weak laser intensities and small Lamb-Dicke parameters. To overcome this limitation, we present the concept of dark polarons: spatially extended states of pseudospin polarization that are fully decoupled from a lambda laser configuration. In this picture, all high-order Lamb-Dicke terms collapse into a single linear coupling independent of laser intensity. We apply it to definitively elucidate the reasons behind cooling rate limitations observed in recent experimental implementations of electromagnetically induced transparency with high-intensity lasers.
