Query: SU(2) Charges with Spherical Symmetry and Confining Boundary Conditions   Applying the static Yang-Mills Maxwell equations to a simple system of SU(2)
charges with spherical symmetry and confining boundary conditions provides for
a demonstration of the likelihood that the confinement mechanism in non-Abelian
gauge theories necessarily involves a topologically-charged domain wall
consisting of a surface volume with CP-odd field strength density. The surface
volume of a color-singlet system of SU(2) charges therefor describes the
magnetic dual of a topological insulator. This essential topological structure
in inextricably connected to the hadronic dynamics of the pion tornado. In
analogy to the kink solution in the 1+1 dimensional Abelian Higgs model the
classical solutions for the field equations in spherically symmetric SU(2) with
this domain wall of topological charge can lead to a mass gap in the quantum
system
