Integrable open spin chains from giant gravitons

TL;DR

This paper demonstrates that open strings attached to giant gravitons in N=4 SYM correspond to an integrable PSU(2,2|4) open spin chain with boundary conditions, at least at one loop in the SO(6) sector.

Contribution

It establishes the integrability of the open spin chain model arising from giant gravitons in N=4 SYM at one loop order.

Findings

Open strings attached to giant gravitons map to an integrable spin chain.

The integrability holds with specific boundary conditions in the SO(6) sector.

The result is valid at one loop order.

Abstract

We prove that in the presence of a maximal giant graviton state in N=4 SYM, the states dual to open strings attached to the giant graviton give rise to an PSU(2,2|4) open spin chain model with integrable boundary conditions in the SO(6) sector of the spin chain to one loop order.
