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…
Short Strings in Three-Dimensional Anti-de Sitter Space: from Weak to Strong Coupling
Simon Ekhammar, Nikolay Gromov, Bogdan StefaÅski +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…
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 StefaÅski
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…
