Recently, gauge field theory approaches were extensively used in order to discuss some physical consequences of spinorbit interactions in condensed matter physics. An SU(2)\times U(1) gauge theory very naturally comes out and provides an illustrative example of a classical YangMills field theory at work. This approach may serve as an exemplification of nonAbelian field theories for students in general physics curriculum. It allows to introduce discussions on fundamental ideas like Noether currents, gauge symmetry principle, gauge symmetry breaking or non linear Yang Mills equations in very concrete situations which make it accessible for a general audience.
