- Open Quantum Dynamics and Spontaneous Symmetry Breaking
Abstract: Open quantum systems fundamentally differ from closed systems in that they allow for the creation and destruction of information. This unique property has led to the discovery of various information-theoretic phase transitions, sparking significant interest and research in the field. In this talk, I will introduce strong-to-weak spontaneous symmetry breaking (SSB) as a unifying framework for understanding these information-theoretic transitions. By outlining this general framework, we will explore how it applies to several key phenomena, including purification dynamics, charge-sharpening dynamics, quantum error correction, and fault-tolerance thresholds. This approach not only unifies disparate concepts but also advances our comprehension of open quantum dynamics.
Bio: Jong Yeon Lee received his bachelor's degree in Physics and Mathematics from Caltech in 2015, earning the Richard P. Feynman Prize. He completed his Ph.D. at Harvard in 2020, focusing on exotic phenomena in quantum many-body systems. From 2020 to 2023, he was a postdoc at the Kavli Institute for Theoretical Physics, studying decohered quantum systems and their information-theoretic capacities. In 2023, he joined the University of Illinois, where he researches the intersection of condensed matter physics and quantum information science.
