Description
The dual superconductor picture is a promising mechanism for quark confinement, and magnetic monopoles play a dominant role in quark confinement. To understand the mechanism of quark confinement, we investigate the relation between the violation of the non-Abelian Bianchi identity (VNABI), the emergence of magnetic monopoles, and confinement by using the gauge-covariant decomposition and the non-Abelian Stokes theorem for the Wilson loop.
We find that the VNABI is reduced to the magnetic monopoles associated with the color-direction fields. Therefore, the emergence of magnetic monopoles causes the VNABI, which contributes to quark confinement. We further conduct numerical simulations and provide numerical evidence.
