Anffany Chen, Ph.D. Physics

Hi there, I am a researcher in theoretical physics who has explored various phases of quantum matter, such as those exhibiting superconductivity, spin frustration, topological order, and localization. Recently I have been especially interested in the intersection of physics and machine learning.
