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.
