Abstract :

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

qubits.
