Unfortunately, this talk had to be cancelled!

Massless fermions carry a particular property, known as chirality, relating their spin and momentum. In addition, this property is intimately related to the topology of the gauge fields these fermions interact with. In the presence of quantum anomalies this interplay may lead to the appearance of anomalous transport phenomena, such as the Chiral-Magnetic-Effect (CME) [1].

Here we report on a study of a particular manifestation of anomalous transport, so called chiral instabilities [2], which may play a role in relativistic heavy-ion collisions and the formation of neutron stars with extremely large magnetic fields. Using lattice simulation techniques [3] we find evidence for the existence of these instabilities in SU(2) gauge theory and explore their properties.
