On the scaling behaviour of the alternating spin chain

Bazhanov, Vladimir; Kotousov, Gleb; Koval, Sergii; Lukyanov, Sergei L


In this note we report the results of our study of a 1D integrable spin chain whose critical behaviour is governed by a CFT possessing a continuous spectrum of scaling dimensions. It is argued that the computation of the density of Bethe states of the continuous theory can be reduced to the calculation of the connection coefficients for a certain class of differential equations whose monodromy properties are similar to those of the conventional confluent hypergeometric equation. The finite size...[Show more]
