Xuejian Wu is an experimental atomic physicist. His research aims to advance quantum sensors to new regimes with unprecedented sensitivity, miniaturized size, turn-key operation, and versatile functions, and apply them for metrology, navigation, geophysics, and biology. 

The Wu Lab (sites.google.com/view/wulabrun/) at Rutgers-Newark Physics is always looking for motivated students, postdocs, and visitors. Please contact Xuejian Wu for more information!

Currently, we are building a light-pulse atom interferometer with atoms above an optical nanofiber. We will use the evanescent wave guided by the optical nanofiber to coherently manipulate the surrounding atoms and form matter-wave interferometry. This quantum sensor can be used for measuring accelerations and rotations in applications such as inertial navigation. Additionally, we are interested in developing portable quantum inertial sensors and electromagnetic field detectors for geological surveys, underground water storage estimations, and volcano activity monitors. Using structured and squeezed light, we are interested in building high resolution microscopy and spectroscopy instruments for visualizing cell mechanics, particle dynamics, and material chemical structures.
