报告人简介：
Chiang-Mei Chen, Professor in the Department of Physics at National Central University (NCU), Taiwan. He received his Ph.D. from Moscow State University in 1999 and subsequently conducted postdoctoral research at NCU and National Taiwan University. He joined the faculty of NCU in 2003. His research focuses on theoretical gravitational physics, including black hole physics and cosmology. Recently, his work has concentrated on the Schwinger effect in charged black holes, quantum-improved black holes and cosmological models involving running coupling constants.

报告摘要：
In this talk, I will explore quantum-improved black hole solutions within the framework of asymptotic safety. In this approach, the Newton coupling becomes scale-dependent, necessitating a meaningful identification between the energy scale and a corresponding physical (length) scale to derive observable consequences for black hole spacetimes. I will argue that the requirement of consistency with the first law of black hole thermodynamics provides a physically motivated criterion for this scale-setting, particularly near the event horizon. Applying this principle, we propose a specific identification scheme that leads to a regularized geometry capable of resolving the ring singularity of Kerr black holes.
