Michel Gaudin is recognised as one of the foremost experts in this field, and has worked at Commissariat a l'energie atomique (CEA) and the Service de Physique Theorique, Saclay. His numerous scientific contributions to the theory of exactly solvable models are well-known, including his famous formula for the norm of Bethe wavefunctions. Jean-Sebastien Caux is a professor of the theory of low-dimensional quantum condensed matter at the University of Amsterdam. He has made significant contributions to the calculation of experimentally observable dynamical properties of these systems.
'The book presents in detail many important computations. This allows the beginner in the field to learn many of the techniques that are relevant for new applications. … [This] is an outstanding book which every library should have. It will be extremely useful both for graduate and postgraduate students. The book can also serve as a source of inspiration for an advanced physics course on integrable models both in condensed matter theory and statistical physics. The translator has done a great job making this book accessible to the much wider audience it deserves.' Gunter M. Schütz, Contemporary Physics
