报告题目/Title: Precision Frontier for New Physics Search 

摘要/Abstract:

Dark matter (DM) comprises approximately 27% of the energy in the observable universe. Unveiling the properties of DM is one of the most important tasks in modern physics. Benefiting from the rapid developments of the precision frontier, especially through the techniques of quantum sensing, it has become possible to probe large unexplored parameter space of dark matter. Among DM candidates, dark photon dark matter is particularly promising. I will first demonstrate how to utilize a resonant (LC-circuit) and a broad- band (SERF) electromagnetic detector to search for the kinetically mixed dark photon DM. Both proposals are already realized, and promising results are delivered. In addition, a gravitational wave detector (LIGO) or an optomechanical system can also be used to efficiently search for the U(1)_{B-L} dark photon DM, as well as other species of ultralight DM candidates such as dilaton and axion. The results from these two methods deliver the world records in certain parameter space.

报告人简介/Curriculum Vitae:

Dr. Zhao received his bachelor's degree from Peking University in 2007 and his Ph.D. from Rutgers University in 2012. He then held postdoctoral positions at Stanford University/SLAC and the University of Michigan before joining the University of Utah as a faculty in 2018. In 2025, he joined HKUST as an associate professor. His research spans a wide range of disciplines, with a particular focus on innovative strategies for searching for dark matter and exploring new physics beyond the Standard Model of particle physics. He also leads the LIGO gravitational wave group at HKUST. As a theorist, he collaborates closely with experimentalists.
