Short Strings in Three-Dimensional Anti-de Sitter Space: from Weak to Strong Coupling
Simon Ekhammar, Nikolay Gromov, Bogdan Stefański +1
We numerically solve the conjectured Quantum Spectral Curve for strings on AdSST with R--R charge from weak to strong coupling. At strong coupling, the spec…
Twisting the Hagedorn temperature in planar super Yang-Mills
Simon Ekhammar, Joseph A. Minahan, Charles Thull
We consider planar super Yang-Mills at finite temperature with chemical potentials that couple either to the -charges or the spins of the operators. We find expr…
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…
Gluing Quantum Spectral Curves: A Two-Copy osp(4|2) Construction
Filipp Chernikov, Simon Ekhammar, Nikolay Gromov +1
We propose a Quantum Spectral Curve for planar string theory on AdS3*S3*S3*S1 supported by pure Ramond-Ramond flux. Our proposal is built on symmetry considerations and integrabili…
Regge Trajectories of N=4 SYM Part I: General Asymptotic Baxter-Bethe Ansatz
Simon Ekhammar, Nikolay Gromov, Michelangelo Preti
In this work, we derive a novel set of equations - the Asymptotic Baxter--Bethe Ansatz - that determine the asymptotic spectrum of Regge trajectories in the BFKL regime of N=4 SYM.…
Demystifying the Massless Sector in AdS_3 Quantum Spectral Curve
Simon Ekhammar, Nikolay Gromov, Bogdan Stefański
We show that in the asymptotic large-volume limit, the original proposal for Quantum Spectral Curve for AdS3 x S3 x T4 with R-R flux has a wider class of solutions, than studied pr…
Long Range Asymptotic Baxter-Bethe Ansatz for N=4 BFKL
Simon Ekhammar, Nikolay Gromov, Michelangelo Preti
We demonstrate that the Balitsky-Fadin-Kuraev-Lipatov regime of maximally supersymmetric Yang-Mills theory can be explicitly solved up to the L+1 order in weak coupling by uncoveri…
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…
The ABJM Hagedorn Temperature from Integrability
Simon Ekhammar, Joseph A. Minahan, Charles Thull
We use the quantum spectral curve to compute the Hagedorn temperature for ABJM theory in terms of the interpolating function . At weak coupling we compute this temperature up…
The asymptotic form of the Hagedorn temperature in planar super Yang-Mills
Simon Ekhammar, Joseph A. Minahan, Charles Thull
Using the supergravity dual and the plane-wave limit as a guide, we conjecture the asymptotic large coupling form of the Hagedorn temperature for planar super Yang-…
Exploring the Quantum Spectral Curve for AdS/CFT
Andrea Cavaglià, Simon Ekhammar, Nikolay Gromov +1
Despite the rich and fruitful history of the integrability approach to string theory on the background, it has not been possible to extract many concret…
Monodromy Bootstrap for SU(2|2) Quantum Spectral Curves: From Hubbard model to AdS3/CFT2
Simon Ekhammar, Dmytro Volin
We propose a procedure to derive quantum spectral curves of AdS/CFT type by requiring that a specially designed analytic continuation around the branch point results in an automorp…
On the squashed seven-sphere operator spectrum
Simon Ekhammar, Bengt E. W. Nilsson
We derive major parts of the eigenvalue spectrum of the operators on the squashed seven-sphere that appear in the compactification of eleven-dimensional supergravity. These spectra…
Bethe Algebra using Pure Spinors
Simon Ekhammar, Dmytro Volin
We propose a gl(r)-covariant parameterisation of Bethe algebra appearing in so(2r) integrable models, demonstrate its geometric origin from a fused flag, and use it to compute the…
Extended systems of Baxter Q-functions and fused flags I: simply-laced case
Simon Ekhammar, Hongfei Shu, Dmytro Volin
The spectrum of integrable models is often encoded in terms of commuting functions of a spectral parameter that satisfy functional relations. We propose to describe this commutativ…
