It is shown that superconductivity offers a way to avoid this cancellation of the chiral magnetic effect by means of a flux bias that gaps out a Weyl cone jointly with its particle-hole conjugate.

Geometric phase from Aharonov–Bohm to Pancharatnam–Berry and beyond

- PhysicsNature Reviews Physics
- 2019

Whenever a quantum system undergoes a cycle governed by a slow change of parameters, it acquires a phase factor: the geometric phase. Its most common formulations are known as the Aharonov-Bohm,…
