Chirality is a ubiquitous concept in modern science, from particle physics to biology.
In quantum physics, chirality is linked to the topology of gauge fields due to the
quantum chiral anomaly. While the chiral anomaly is usually associated with the
short-distance behavior, recently it has been realized that it affects also the macroscopic
behavior of systems possessing chiral fermions. In particular, the local imbalance
between left- and right-handed fermions in the presence of magnetic field induces
the non-dissipative transport of electric charge ("the Chiral Magnetic Effect").
In heavy ion collisions, there is an ongoing search for this effect at Relativistic Heavy
Ion Collider at BNL, with a dedicated isobar run completed in June of 2018, and
analysis results expected later in 2019. Recently, the Chiral Magnetic Effect has been
discovered in ZrTe5 and other materials possessing chiral quasi-particles.
This observation opens a path towards a "chiral qubit" potentially capable of operating
at room temperature, and at much higher frequencies than the superconducting quantum
