The chiral magnetic effect: possible connections between heavy ion physics
and condensed matter
Dra. Ana Mizher, Instituto de Física Teórica,

The chiral magnetic effect (CME) is a non-dissipative electric current that
might emerge as a result from an imbalance of chirality associated with a
magnetic background in the quark-gluon plasma. Despite over a decade of
efforts, to define unambiguous observables of the CME in heavy ion
collisions turned out to be a hard task. On the other hand, with the
discovery of Dirac and Weyl semimetals in condensed matter, where the
quasiparticles behave relativistic-like, a link between high energy physics
and condensed matter was constructed and an analog of the CME was clearly
observed in (3+1)D Dirac/Weyl materials. In this talk I present a new
mechanism to generate an anomalous Quantum Hall Effect in two-dimensional
materials, inspired by the CME. Promising candidates that may intrinsically
harbour this (topologically protected) effect are also presented.
