As an illustrating example, we consider a charged massless complex scalar coupled to U(1) gauge theory in $\\mathbb{R}^{1,3}\\times {\\mathbb S}^1$ and discuss the effect of background gauge potential along a compact direction. The electric field produces the charged Kaluza-Klein particle non-perturbatively, which we call KK Schwinger effect.
