Wilson line correlators in two-dimensional noncommutative Yang-Mills theory
We study the correlator of two parallel Wilson lines in two-dimensional noncommutative Yang-Mills theory, following two different approaches. We first consider a perturbative expansion and resum all planar diagrams, planarity acquiring a meaning in two dimensions only in the large-N limit. The second approach is non-perturbative: we exploit the Morita equivalence, mapping the two open lines on ...
متن کاملImaginary parts and discontinuities of Wilson line correlators.
We introduce a notion of position-space cuts of eikonal diagrams, the set of diagrams appearing in the perturbative expansion of the correlator of a set of straight semi-infinite Wilson lines. The cuts are applied directly to the position-space representation of any such diagram and compute its imaginary part to the leading order in the dimensional regulator. Our cutting prescription thus defin...
متن کاملTwo-dimensional non-commutative Yang-Mills theory: coherent effects in open Wilson line correlators
A perturbative calculation of the correlator of three parallel open Wilson lines is performed for the U(N) theory in two non-commutative space-time dimensions. In the large-N planar limit, the perturbative series is fully resummed and asymptotically leads to an exponential increase of the correlator with the lengths of the lines, in spite of an interference effect between lines with the same or...
متن کاملWilson loop correlators at strong coupling: from matrices to bubbling geometries
We compute at strong coupling the largeN correlation functions of supersymmetric Wilson loops in large representations of the gauge group with local operators of N = 4 super Yang-Mills. The gauge theory computation of these correlators is performed using matrix model techniques. We show that the strong coupling correlator of the Wilson loop with the stress tensor computed using the matrix model...
متن کاملThe Wilson-Wilson Experiment
An example of unipolar induction is a slab of material with (relative) permittivity and (relative) permeability μ that is immersed in a uniform external magnetic field H0 parallel to the plane of the slab, such that if the slab has velocity v perpendicular to H0 but also in the plane of the slab, a nonzero voltage difference V is detected between sliding contacts (fixed in the laboratory) on op...
