  Chirality is a ubiquitous concept in modern science, from particle physics to
biology. In quantum physics, chirality of fermions is linked to topology of
gauge fields by the chiral anomaly. While the chiral anomaly is usually
associated with the short-distance behavior in field theory, in recent years it
has been realized that it also affects the macroscopic behavior of systems with
chiral fermions. In particular, the local imbalance between left- and
right-handed fermions in the presence of a magnetic field induces
non-dissipative transport of electric charge ("the Chiral Magnetic Effect",
CME). In heavy ion collisions, there is an ongoing search for this effect at
Relativistic Heavy Ion Collider, with results from a dedicated isobar run
presented very recently. An observation of CME in heavy ion collisions could
shed light on the mechanism of baryon asymmetry generation in the Early
Universe. Recently, the CME has been discovered in Dirac and Weyl semimetals
possessing chiral quasi-particles. This observation opens a path towards
quantum sensors, and potentially a new kind of quantum computers.
