Novel Atom Interferometry Techniques

伯明翰大学与丰田汽车欧洲公司合作，提供了一个博士职位，为高数据速率量子重力仪开发新的原子干涉测量技术，旨在实现重力地图匹配导航和其他应用。量子重力传感器在基础物理研究以及包括地球科学和土木工程在内的不同学科中都表现出了非凡的稳定性和精确度。最近，人们开始探索量子重力传感器在更动态的环境中的潜力，如海洋和空中环境。一个特殊的应用是重力地图匹配导航。卫星导航在20世纪80年代末向民用开放后，很快就变得非常流行。其他技术，包括惯性导航和地图匹配导航，由于卫星导航系统的弱点，例如卫星信号在复杂地形中的接收、易受干扰和欺骗，仍然受到相当大的关注。然而，惯性传感器的漂移严重影响了惯性导航的精度。重力地图匹配技术通过不断跟踪车辆轨迹上的重力变化并将其与重力地图进行比较，帮助惯性导航系统抑制漂移问题。伯明翰大学与丰田汽车欧洲公司合作，提供了一个博士职位，为高数据速率量子重力仪开发新的原子干涉测量技术，旨在实现重力地图匹配导航和其他应用。成功的候选人将研究新的原子干涉测量技术，以解决与在动态环境中运行的重力仪相关的问题，并改进目前的重力仪设计。他/她可能参与先进的原子光学的发展，以提高灵敏度。除了实验工作外，他/她还将花费大量时间进行概念验证的模拟。

The University of Birmingham, in partnership with Toyota Motor Europe, is offering a PhD position for developing novel atom interferometry techniques for a high-data-rate quantum gravimeter aiming for gravity map-matching navigation and other applications. Quantum gravity sensors have manifested their exceptional stability and precision for fundamental physics research and also different disciplines, including geoscience and civic engineering. More recently, people started exploring the potential of quantum gravity sensors in more dynamic settings such as marine and airborne environments. One particular application is gravity map-matching navigation. Satellite navigation (Satnav) soon became very popular after it was open to civilian use in the late 1980s. Other technologies, including inertial and map-matching navigations, still receive substantial attention because of Satnav weaknesses, e.g. the satellite signal reception in difficult terrain, proneness to interference and spoofing. Nevertheless, drifts of inertial sensors severely hamper the accuracy of inertial navigation. The gravity map-matching technology assists inertial navigation systems to curb the drift issue by constantly tracking the gravity variation along the vehicle trajectory and comparing it with a gravity map. The University of Birmingham, in partnership with Toyota Motor Europe, is offering a PhD position for developing novel atom interferometry techniques for a high-data-rate quantum gravimeter aiming for gravity map-matching navigation and other applications. The successful candidate will study novel atom interferometry techniques to address the issues related to the gravimeter operating in dynamic environments and to improve the current gravimeter design. He/she may be involved in the development of advanced atom optics to increase sensitivity. Apart from the experimental work, he/she will spend a substantial amount of time on simulation for concept validation.
