Towards realistic boundary conditions of the chiral magnetic effect*

The Chiral Magnetic Effect (CME) -- the separation of positive and negative electric charges along the direction of the external magnetic field in quark-gluon plasma  -- is a consequence of the coupling of electrodynamics to the topological gluon field fluctuations that form metastable CP-odd domains. I argue, using a simple model consisting of a uniform spherical domain in a uniform time-dependent magnetic field, that the boundary conditions on the domain walls play a crucial role in the CME dynamics and have a profound phenomenological effect.
