Contribution

It introduces a method to compute two-point functions for spinning strings that aligns with gauge theory spin chain results, enhancing holographic correspondence insights.

Findings

Two-point functions match spin chain predictions

Spinning string solutions start and end at the boundary

Method confirms bulk-boundary correspondence in large J limit

Abstract

We study the holographic principle of the two-point function in the case of a spinning string in the AdS/CFT correspondence. Following the general method proposed by Yoneya et al. for the bulk-boundary correspondence in the large $J$ limit, we study the spinning string solution which starts and ends at the boundary. We then show that the spinning string solution directly gives a two-point function that is consistent with the spin chain picture in gauge theory.
