THE BOOKS

A.A. Zvyagin, Finite Size Effects in Correlated Electron Models: Exact Results
(Imperial College Press, London, & World Scientific, Singapore, 2005).

This book presents to the reader main methods of the modern condensed matter theory for low-dimensional correlated electron systems: the Bethe's ansatz (BA), with main its modifications: co-ordinate BA, nested BA, thermodynamic BA, algebraic BA (or the quantum inverse scattering method), thermal BA (or the quantum transfer matrix approach); scaling; conformal field theory; Abelian and non-Abelian bosonization, etc.

A.A. Zvyagin “Quantum Theory of One-Dimensional Spin Systems”
(Cambridge Scientific Publishers, Cambridge, 2010).

This book is devoted to the description of low-dimensional quantum spin systems. Its first
part reminds the reader the main issues of magnetism: basics of thermodynamics, electrodynamics, quantum mechanics of magnetic media. In the second part I describe
exact theoretical results for models of quantum spin chains. Finally, the third part is devoted to applications of those exact results to the characteristics of more realistic models of
quasi-one-dimensional quantum spin systems.
