Explore the fundamental principles of chiral Luttinger liquid theory in this comprehensive lecture delivered by Prof. Biao Lian from Princeton University as part of the Princeton Summer School for Condensed Matter Physics. Delve into the intricate world of one-dimensional quantum many-body systems where interactions between particles lead to exotic quantum phases and emergent phenomena. Learn how chiral edge states in quantum Hall systems and topological insulators can be described using Luttinger liquid theory, examining the role of electron-electron interactions in determining the low-energy physics of these systems. Discover the mathematical framework underlying chiral Luttinger liquids, including bosonization techniques and the renormalization group approach to understanding correlation functions and transport properties. Investigate various interaction-driven phases that can emerge in these systems, from conventional Luttinger liquid behavior to more exotic states with fractionalized excitations. Gain insights into experimental signatures of chiral Luttinger liquid physics and their relevance to current research in condensed matter physics, particularly in the context of quantum Hall edge states and topological quantum matter.
