  "abstract": "A bstract : 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 we derive operatorially from the underlying 𝔰𝔩(2) spin chain. These equations are reminiscent of the Quantum Spectral Curve framework found in other holographic conformal field theories and are expected to provide a complete non-perturbative description of the spectrum at arbitrary coupling. We solve our equations numerically at finite coupling and uncover a rich analytic structure, including state collisions and complex energy levels. Analytically, we introduce a new method to derive the Asymptotic Bethe Ansatz equations, which control the spectrum up to wrapping order and incorporate spinning states. We further extend our results to the twisted case, which may be particularly useful for future separation of variables analyses of correlation functions in this theory.",
