Abstract

We construct a basis of solutions of the scalar tQ\boldsymbol{ \texttt{t} }- \boldsymbol{ \texttt{Q} } equation describing the spectrum of the qq-Toda and Toda2_2 chains by using auxiliary non-linear integral equations. Our construction allows us to provide quantisation conditions for the spectra of these models in the form of thermodynamic Bethe Ansatz-like equations.
