Interacting Double Coset Magnons
Abdelhamid Mohamed Adam Ali, Robert de Mello Koch, Nirina Hasina Tahiridimbisoa +1
We consider the anomalous dimensions of restricted Schur polynomials constructed using n~O(N) complex adjoint scalars Z and m complex adjoint scalars Y. We fix m<<n so that our ope…
Interactions as conformal intertwiners in 4D QFT
Robert de Mello Koch, Sanjaye Ramgoolam
In a recent paper we showed that the correlators of free scalar field theory in four dimensions can be constructed from a two dimensional topological field theory based on so(4,2)…
Anomalous Dimensions of Heavy Operators from Magnon Energies
Robert de Mello Koch, Nirina Hasina Tahiridimbisoa, Christopher Mathwin
We study spin chains with boundaries that are dual to open strings suspended between systems of giant gravitons and dual giant gravitons. The anomalous dimensions computed in the g…
