BMN Operators from Wilson Loop
We show that the BMN operators arise from the expansion of the Wilson loop in four-dimensional N = 4 super Yang-Mills theory. The Wilson loop we consider is obtained from “dimensional reduction” of ten-dimensional N = 1 super YangMills theory, and it contains six scalar fields as well as the gauge field. We expand the Wilson loop twice. First we expand it in powers of the fluctuations around a ...
متن کاملBoundary condition for D-brane from Wilson loop, and gravitational interpretation of eigenvalue in matrix model in AdS/CFT correspondence
We study the supersymmetric Wilson loops in the four-dimensional N = 4 super YangMills theory in the context of AdS/CFT correspondence. In the gauge theory side, it is known that the expectation value of the Wilson loops of circular shape with winding number k, Wk(C), is calculable by using a Gaussian matrix model. In the gravity side, the expectation value of the loop is conjectured to be give...
متن کاملMeasurability of Wilson loop operators
We show that the nondemolition measurement of a spacelike Wilson loop operator W(C) is impossible in a relativistic non-Abelian gauge theory. In particular, if two spacelike-separated magnetic flux tubes both link with the loop C, then a nondemolition measurement of W(C) would cause electric charge to be transferred from one flux tube to the other, a violation of relativistic causality. A destr...
متن کاملOne-loop effective brane action
The one-loop effective action for a p brane embedded in a D = p+2 Minkowski spacetime in the static gauge is calculated. Rescaling the quantum fluctuation by −g0 evaluated on the background brane leads to the one-loop effective action expressed only in terms of infrared and ultraviolet divergent geometric scalars. After the infrared divergences are absorbed into the quantum fluctuation, there r...
متن کاملWilson Loop on a Light-Cone Cylinder
QCD without matter and quantized on a light-cone spatial cylinder is considered. For the gauge group SU(N) the theory has N − 1 quantum mechanical degrees of freedom, which describe the color fux that circulates around the the spatial cylinder. In 1+1 dimensions this problem can be solved analytically. I use the solution for SU(2) to compute the Wilson loop phase on the surface of the cylinder ...
