Yafei Ren

Yafei Ren is an Assistant Professor in the Department of Physics & Astronomy at the University of Delaware, part of the College of Arts & Sciences. She holds a B.S. and Ph.D. from the University of Science and Technology of China and joined UD in August 2023. Her research focuses on geometric phase effects and nonequilibrium phenomena in condensed matter systems, particularly electron-phonon-coupled systems with applications in spintronics, magnonics, and phononics.

Her research interests include the study of topological materials, nonlinear magnonic processes, and the interplay between magnetism and band topology. Notable projects involve engineering corner states in topological insulators, exploring exciton-magnon coupling in layered semiconductors, and investigating light-driven phonon chirality in paramagnetic systems.

Ren's work spans theoretical and applied condensed matter physics, with a focus on quantum materials and their novel functionalities. Her recent publications highlight advancements in topological phase transitions, orbital magnetization dynamics, and the design of higher-order topological insulators. She advises several graduate students and postdocs, including Saurabh, Randy, Will, Ali Kefayati, and Sanjib Das.
