Po-Shen Hsin

Po-Shen Hsin is a Lecturer in the Department of Mathematics at King’s College London. He holds a BSc in Physics from National Taiwan University (2012), an MA in Physics from Princeton University (2016), and a PhD in Physics from Princeton University (2018). His research focuses on theoretical physics, particularly quantum field theory, strongly interacting systems, topological phases of matter, and the interplay of symmetries and anomalies. He explores topics such as non-invertible symmetries, higher-form anomalies, and their implications for topological phases and condensed matter systems.

His work spans theoretical frameworks like gauge theories, topological defects, and quantum error correction codes, with applications to understanding exotic phenomena in materials and high-energy physics. Notable themes include symmetry-enriched topological phases, anomaly detection, and the classification of logical gates in quantum codes via cohomology operations.

His research group at King’s College is part of the broader efforts in supersymmetry, string theory, and related areas within the Faculty of Natural, Mathematical & Engineering Sciences. His contributions bridge fundamental theoretical insights with potential applications in quantum technologies and condensed matter systems.
