Matter-wave interferometry is among the most advanced technologies for precision measurements. Light-pulse atom interferometry uses the recoil momentum from photon-atom interactions to coherently split and recombine matter waves. It has been used for measuring gravity, the gravity gradient, rotation, fundamental constants, and for testing fundamental laws of physics in well-controlled laboratories. New applications, such as geodesy, geology, or inertial navigation, are foreseeable with robust, mobile, and versatile quantum sensors. In this talk, I will present atom interferometers for measuring the fine structure constant, constraining on dark energy, and sensing inertial forces. Particularly, I will elaborate a multiaxis atom interferometer toward deployable quantum sensors for field applications. |

Dr. Xuejian Wu is a Postdoc Fellow in Physics Department at UC Berkeley. He received his PhD in the Department of Precision Instruments at Tsinghua University in 2015, where he worked on laser interferometry for measuring the absolute diameter of a silicon sphere to determine the Avogadro constant. Since January 2015, Dr. Wu has worked on a transportable gravimeter based on atom interferometry. |
