PP-Waves and Holography
نویسندگان
چکیده
We consider aspects of holography in the pp-wave limit of AdS5 × S. This geometry contains two R’s, one obtained from AdS5 directions, and the other from the S. We argue that the holographic direction in the pp-wave background can be taken to be r, the radial direction in the first R. Normalizable modes correspond to states, and non-normalizable modes correspond to deformations of the boundary theory. In the strict pp-wave limit, there are additional non-normalizable modes in the second R, which have no apparent super-Yang-Mills interpretation. We outline the procedure for calculating correlation functions holographically.

Quasi-local holography and quasi-local mass of classical fields in Minkowski spacetime
The 2-surface characterization of special classical radiative Higgs-, Yang–Mills and linear zero-rest-mass fields with any spin is investigated. We determine all the zero quasi-local mass Higgsand Yang–Mills field configurations with compact semisimple gauge groups, and show that they are plane waves (provided the Higgs field is massless and linear) and appropriate generalizations of plane wave...

متن کاملStrings in homogeneous gravitational waves and null holography
Homogeneous gravitational wave backgrounds arise as infinite momentum limits of many geometries with a well-understood holographic description. General global aspects of these geometries are discussed. Using exact CFT techniques, strings in pp-wave backgrounds supported by a Neveu-Schwarz flux are quantized. As in Euclidean AdS3, spectral flow and associated long strings are shown to be crucial...
متن کاملHolography and Colliding gravitational shock waves in asymptotically AdS5 spacetime.
Using holography, we study the collision of planar shock waves in strongly coupled N=4 supersymmetric Yang-Mills theory. This requires the numerical solution of a dual gravitational initial value problem in asymptotically anti-de Sitter spacetime.
متن کاملEvidence for the existence of localized plastic flow au-to-waves generated in deforming metals
The localized plastic flow auto-waves observed for the stages of easy glide and linear work hardening in a number of metals are considered. The propagation rates were determined experimentally for the auto-waves in question with the aid of focused-image holography. The dispersion relation of quadratic form derived for localized plastic flow auto-waves and the dependencies of phase and group rat...
