  The heavy ion collision provides a unique many-body environment where local
domains of strongly interacting chiral medium may occur and in a sense allow
environmental symmetry "violation" phenomena. For example certain anomalous
transport processes, forbidden in usual medium, become possible in such
domains. We briefly review recent progress in both the theoretical
understanding and experimental search of various anomalous transport effects
(such as the Chiral Magnetic Effect, Chiral Separation Effect, Chiral Electric
Separation Effect, Chiral Electric/Magnetic Waves, etc) in the hot QCD fluid
created by such collisions.
