  The prerequisite of the chiral magnetic effect is the existence of net chiral
charge in the quark gluon plasma (QGP). If we assume the quarks and anti-quarks
contribute equally to the net chiral charge, the CME will induce a flow of the
quark chemical potential and will cause the QGP having three distinct layers
along the strong magnetic field characterised by distinctive compositions of
quark chemical potentials. This phenomenon may bring new observable outcomes
and help us test the existence of CME.
