Quark Anti-Quark Fusion and Walking RG Flows
Filipp Chernikov, Nikolay Gromov, Amit Sever
We study the fusion of two conjugate conformal line defects on the sphere. At small separation, their spectrum is governed by a universal Fusion Master Equation. Below a critical c…
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…
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.…
Probing Line Defect CFT with Mixed-Correlator Bootstrability
Andrea CavagliÃ, Nikolay Gromov, Julius Julius +2
We continue our study of the defect CFT on a Maldacena-Wilson line in N=4 Super-Yang-Mills theory using Bootstrability -- the conformal bootstrap supplemented with exact integrabil…
