Decoherence of a central spin in solids is not only an ideal model problem for understanding the foundation of quantum physics but also a critical issue in quantum information technologies.Studying central spin decoherence caused by environmental fluctuations may yield key insights into the nature of many-body interactions in the environment.Furthermore,dynamical control over the central spin can affect the dynamics of the environment in a detectable manner.In the light of these ideas,exploiting central spin decoherence for sensing single nuclear spins has been demonstrated.Recently,this idea has been pushed to new depths:theoretical studies show that the central spin decoherence can be a novel probe to many-body physics,in particular,phase transitions in spin baths.Multiple-spin correlations are one of the essential characteristics in spin baths,but detection of such correlations is a long-standing challenge in many-body physics.

毛细管电泳(CE)的核心是电渗流,由于CE中电渗流的不稳定性,因此CE的重现性一般劣于色谱分析(例如高效液相色谱和气相色谱),这限制了CE在常规分析中的应用。在本工作中,我们利用高压泵和六通进样阀建立了一个加压毛细管电泳系统,引入高精度的压力流以改善重现性,提高分析效率。论文第一章从毛细管电泳的分离原理、分离模式、操作及检测方法等几方面进行了综述。第二章介绍了加压毛细管电泳系统的设计思路,并和紫外
