Abstract

We solve N = (8, 8) super-Yang-Mills theory in 1 + 1 dimensions at strong coupling to directly confirm the predictions of supergravity at weak coupling. We do our calculations in the large-N_c approximation using Supersymmetric Discrete Light-Cone Quantization with up to 3 × 10 ¹² basis states. We calculate the stress-energy correlator 〈T⁺⁺(r)T⁺⁺(0)〉 as a function of the separation r and find that at intermediate values of r the correlator behaves as r ^-5 to within errors as predicted by weak-coupling supergravity. We also present an extension to significantly higher resolution of our earlier results for the same correlator in the N = (2, 2) theory and see that in this theory the correlator has very different behavior at intermediate values of r.
