Radial 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...
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 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 کاملHolographic Wilson Loops
We show that all half-BPS Wilson loop operators in N = 4 SYM – which are labeled by Young tableaus – have a gravitational dual description in terms of D5-branes or alternatively in terms of D3-branes in AdS5×S. We prove that the insertion of a half-BPS Wilson loop operator in the N = 4 SYM path integral is achieved by integrating out the degrees of freedom on a configuration of bulk D5-branes o...
متن کاملWilson loops as Precursors
There is substantial evidence that string theory on AdS5 × S5 is a holographic theory in which the number of degrees of freedom scales as the area of the boundary in Planck units. Precisely how the theory can describe bulk physics using only surface degrees of freedom is not well understood. A particularly paradoxical situation involves an event deep in the interior of the bulk space. The event...
