受量子逻辑启发的时空对称性（反）质子测试技术
Quantum logic inspired techniques for spacetime-symmetry tests with (anti-)protons
摘要：
宇宙学观测以及超越标准模型的物理学理论方法为基本对称性的实验测试提供了强大的动力，例如CPT不变性。在这种背景下，欧洲核子研究中心的冷重子反物质的可用性为潘宁阱中质子和反质子的超高精度比较开辟了一条途径。这项工作讨论了一种受量子逻辑技术启发的实验方法，该方法将提高此类实验中的粒子定位和读出速度。该方法允许交感冷却的（反）质子到其量子力学基态，以及读出其自旋排列，取代常用的连续斯特恩-格拉赫效应。这两个功能是通过耦合到激光冷却的“逻辑”离子共同捕获在一个双阱电位。这种技术将提高测量采样率，从而提供具有较低统计不确定性的结果，有助于严格搜索数据中的时间相关变化。这样的测量最终产生极高的敏感性CPT违反系数作用于重子的标准模型扩展，将允许探索以前未测量类型的对称性违反，并将使反物质为基础的轴子类暗物质搜索质量分辨率提高。
英文摘要：
Cosmological observations as well as theoretical approaches to physics beyond the Standard Model provide strong motivations for experimental tests of fundamental symmetries, such as CPT invariance. In this context, the availability of cold baryonic antimatter at CERN has opened an avenue for ultrahigh-precision comparisons of protons and antiprotons in Penning traps. This work discusses an experimental method inspired by quantum logic techniques that will improve particle localization and readout speed in such experiments. The method allows for sympathetic cooling of the (anti-)proton to its quantum-mechanical ground state as well as the readout of its spin alignment, replacing the commonly used continuous Stern-Gerlach effect. Both of these features are achieved through coupling to a laser-cooled `logic' ion co-trapped in a double-well potential. This technique will boost the measurement sampling rate and will thus provide results with lower statistical uncertainty, contributing to stringent searches for time dependent variations in the data. Such measurements ultimately yield extremely high sensitivities to CPT violating coefficients acting on baryons in the Standard-Model Extension, will allow the exploration of previously unmeasured types of symmetry violations, and will enable antimatter-based axion-like dark matter searches with improved mass resolution.
