Stirring the quantum vacuum: Angular Casimir Momentum of a Landau Charge
arXiv:1909.07198 · doi:10.1103/PhysRevResearch.1.033118
Abstract
We consider the angular momentum of a charge q rotating in a homogeneous magnetic field and study the role of the electromagnetic quantum vacuum. Its orbital angular momentum is caused by the recoil of energetic vacuum photons that grows as n^2, i.e. faster than the kinetic angular momentum -2n\hbar of a Landau level.
