String Bits and the Spin Vertex
Yunfeng Jiang, Ivan Kostov, Andrei Petrovskii +1
We initiate a novel formalism for computing correlation functions of trace operators in the planar N=4 SYM theory. The central object in our formalism is the spin vertex, which is…
Semi-classical scalar products in the generalised SU(2) model
Ivan Kostov
In these notes we review the field-theoretical approach to the computation of the scalar product of multi-magnon states in the Sutherland limit where the magnon rapidities condense…
Semi-classical analysis of the inner product of Bethe states
Eldad Bettelheim, Ivan Kostov
We study the inner product of two Bethe states, one of which is taken on-shell, in an inhomogeneous XXX chain in the Sutherland limit, where the number of magnons is comparable wit…
Fixing the Quantum Three-Point Function
Yunfeng Jiang, Ivan Kostov, Florian Loebbert +1
We propose a new method for the computation of quantum three-point functions for operators in su(2) sectors of N=4 super Yang-Mills theory. The method is based on the existence of…
