Solution of Baxter equation for the $q$-Toda and Toda$_2$ chains by NLIE

Abstract : We construct a basis of solutions of the scalar $\boldsymbol{ \texttt{t} }-\boldsymbol{ \texttt{Q} }$ equation describing the spectrum of the $q$-Toda andToda$_2$ chains by using auxiliary non-linear integral equations. Ourconstruction allows us to provide quantisation conditions for the spectra ofthese models in the form of thermodynamic Bethe Ansatz-like equations.
