Twisted Bethe equations from a twisted S-matrix
Changrim Ahn, Zoltan Bajnok, Diego Bombardelli +1
All-loop asymptotic Bethe equations for a 3-parameter deformation of AdS5/CFT4 have been proposed by Beisert and Roiban. We propose a Drinfeld twist of the AdS5/CFT4 S-matrix, toge…
Bethe ansatz equations for open spin chains from giant gravitons
Rafael I. Nepomechie
We investigate the open spin chain describing the scalar sector of the Y=0 giant graviton brane at weak coupling. We provide a direct proof of integrability in the SU(2) and SU(3)…
Two-loop test of the N=6 Chern-Simons theory S-matrix
Changrim Ahn, Rafael I. Nepomechie
Starting from the integrable two-loop spin-chain Hamiltonian describing the anomalous dimensions of scalar operators in the planar N=6 superconformal Chern-Simons theory of ABJM, w…
Analytical Bethe ansatz for the open AdS/CFT SU(1|1) spin chain
Rafael I. Nepomechie, Eric Ragoucy
We prove an inversion identity for the open AdS/CFT SU(1|1) quantum spin chain which is exact for finite size. We use this identity, together with an analytic ansatz, to determine…
Boundary S matrix of an open XXZ spin chain with nondiagonal boundary terms
Rajan Murgan
Using a recently proposed solution for an open antiferromagnetic spin-1/2 XXZ quantum spin chain with N (even) spins and two arbitrary boundary parameters at roots of unity, we com…
Finite-size correction and bulk hole-excitations for special case of an open XXZ chain with nondiagonal boundary terms at roots of unity
Rajan Murgan
Using our solution for the open spin-1/2 XXZ quantum spin chain with N spins and two arbitrary boundary parameters at roots of unity, the central charge and the conformal dimension…
