- Theory Seminar (High Energy/Cosmology)
- Triangle Anomaly in Quark-Gluon Plasma : Chiral Magnetic Wave
- Time: 2:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Ho-Ung Yee, UIC/RIKEN-BNL
- Abstract: Although the effects of triangle anomaly (chiral anomaly) in the chiral effective theory at low temperature are completely accounted for by the Wess-Zumino-Witten action, the physics of triangle anomaly at finite temperature, deconfined phase of QCD is richer and depends more on the dynamics of the theory. We discuss recently discovered new hydrodynamic effects originating from triangle anomaly, Chiral Magnetic Effect and Chiral Magnetic Wave, from several different theoretical viewpoints.
- Physics Department Colloquium
- Topological Phases in Correlated Materials
- Time: 3:30 pm
- Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
- Speaker: Yong-Baek Kim, University of Toronto
- Abstract: Recently there have been significant theoretical and experimental efforts to understand and identify the so-called topological phases of matter in interacting electron systems. These topological phases may be characterized by different kinds of topological properties such as non-trivial edge/surface states and/or unusual elementary excitations in the bulk or surface. Notable examples include quantum spin liquids, topological insulators, and other closely related phases. One of the main challenges is to come up with theoretical criteria that can be used to identify or predict correlated materials that hold promise for the emergence of such topological phases. We discuss recent theoretical and experimental developments in this direction, along with a brief introduction to some of the proposed topological phases. In particular, we focus on correlated materials with strong spin-orbit coupling and/or near a metal-insulator transition.
