Quantum inertial sensors based on light-pulse atom interferometry are powerful tools for precision measurements, navigation, geoscience, and civil engineering. By contrast to classical sensors, atom interferometers use photon momentum to coherently split and recombine matter waves. Since the laser wavelength precisely determines photon momentum, atom interferometers are highly accurate and have demonstrated unprecedented sensitivity and stability. In this talk, I will present compact and versatile atom interferometers for measuring the local gravity field and sensing multi-axis accelerations and rotations. With simplicity and sensitivity, our technology paves the way for deploying quantum sensors in field applications.\n\nBio: Dr. Xuejian Wu joined the Physics Department at Rutgers University-Newark in January 2021.

In the first part of the talk, we will discuss the invariance of Gibbs measures under the cubic nonlinear wave equation. In the second part of the talk, we will then discuss the global well-posedness of the stochastic Yang--Mills heat flow. \n\nThe talk is based on joint works with Y. Deng, A. Nahmod, and H.
