Nov 10, 2016 at 16:44 comment added user32229 @ hongchaniyi, could you give a Ref on what you said? " have the Higgs filed or matter field, the Wilson loop will always behave as the perimeter law?"
Mar 10, 2015 at 9:47 comment added user21090 The wilson loops method doesn't work for a Higgs-gauge model. The reason is when you have the Higgs filed or matter field, the Wilson loop will always behave as the perimeter law.
Aug 24, 2014 at 3:02 comment added Mr. Gentleman I have a question on the Wilson loop approach, do we have to choose the loop to have the shape like a rectangle whose one edge is time $T$ and the other edge is a distance $R$ and require $T\gg R$? In a theory with Lorentz invariance, this choice may not be too important because time and space are not really different. But in a discrete lattice gauge theory we may not have Lorentz invariance, so it seems this choice of the loop is relevant? Another question: can we say confinement comes if the gauge fluctuation is so strong that electric flux can penetrate the system and charges can interact?
