Boundary One-Point Functions in the Open XXZ Spin Chain with Generic Integrable Boundaries
Till Bargheer, Tengis Batmunkh, Paul Ryan
We consider the problem of computing observables beyond the spectrum in the open XXZ spin chain with the most generic integrable boundary conditions. For such boundaries, the resid…
Structure Constants from Q-Systems and Separation of Variables
Till Bargheer, Carlos Bercini, Gabriel Lefundes +1
We introduce a novel method to compute structure constants from Q-functions in the scalar sector of planar N=4 super Yang-Mills (SYM) and related theories. The method derives from…
Integrability and the spectrum of two-dimensional fishnet CFT
Simon Ekhammar, Nikolay Gromov, Fedor Levkovich-Maslyuk +1
We formulate a closed set of equations for the spectrum of two-dimensional bi-scalar fishnet conformal field theory, comprising Baxter equations and quantisation conditions, which…
Orthogonality of Q-Functions up to Wrapping in Planar N=4 Super Yang-Mills Theory
Till Bargheer, Carlos Bercini, Andrea Cavaglià +2
We construct orthogonality relations in the Separation of Variables framework for the sl(2) sector of planar N=4 supersymmetric Yang-Mills theory. Specifically, we find simple univ…
New Approach to Strongly Coupled N = 4 SYM via Integrability
Simon Ekhammar, Nikolay Gromov, Paul Ryan
Finding a systematic expansion of the spectrum of free superstrings on AdSS, or equivalently strongly coupled N = 4 SYM in the planar limit, remains an outstandi…
Boundary Overlaps from Functional Separation of Variables
Simon Ekhammar, Nikolay Gromov, Paul Ryan
In this paper we show how the Functional Separation of Variables (FSoV) method can be applied to the problem of computing overlaps with integrable boundary states in integrable sys…
