Integrability and Wilson loops: the wavy line contour
The Wilson loop with a wavy line contour is studied using integrable methods. The auxiliary problem is solved and the Lax operator is built to first order in perturbation theory, considering a small perturbation from the straight line. Finally the spectral curve of the solution is considered.
متن کاملWilson Loops and Minimal Surfaces
The AdS/CFT correspondence suggests that the Wilson loop of the large N gauge theory with N = 4 supersymmetry in 4 dimensions is described by a minimal surface in AdS5 × S5. We examine various aspects of this proposal, comparing gauge theory expectations with computations of minimal surfaces. There is a distinguished class of loops, which we call BPS loops, whose expectation values are free fro...
متن کاملOn the integrability of Wilson loops in AdS5 × S: Some periodic ansatze
Wilson loops are calculated within the AdS/CFT correspondence by finding a classical solution to the string equations of motion in AdS5×S and evaluating its action. An important fact is that this σ-model used to evaluate the Wilson loops is integrable, a feature that has gained relevance through the study of spinning strings carrying large quantum numbers and spin-chains. We apply the same tech...
متن کاملProduct Integrals and Wilson Loops
Wilson loops provide a convenient method of obtaining gauge invariant observables from lattices to strings. On the other hand the product integral formalism was developed in connection with matrix valued differential equations, having built in the feature of order of the matrices. Consequently these come quite handy when dealing with path ordered quantities. As the theory of product integrals i...
متن کاملRadial propagators and Wilson loops.
We present a relation which connects the propagator in the radial (Fock-Schwinger) gauge with a gauge invariant Wilson loop. It is closely related to the well-known field strength formula and can be used to calculate the radial gauge propagator. The result is shown to diverge in four-dimensional space even for free fields, its singular nature is however naturally explained using the renormaliza...
