Topological and Non-Topological Solitons in Scalar Field Theories

Yakov M. Shnir is the Leading Researcher at the Bogoliubov Laboratory of Theoretical Physics, Joint Institute for Nuclear Research in Dubna and he holds a part time position of Professor of Theoretical Physics at the Belarusian State University in Minsk. His research focuses on topological and non-topological solitons in classical field theory in flat and curved space-time. He has been involved in many of the recent developments in this area, in particular in investigating chaotic structures in dynamics of solitons, construction of knotted solutions in the Bose-Einstein condensate and analysis of thermodynamic properties of hairy black holes.

'Structured in three parts, this book provides a comprehensive introduction to the description and construction of solitons in various models. In the first two chapters of part one, the author discusses the properties of topological solitons in the completely integrable [s]ine-Gordon model and in the non-integrable models with polynomial potentials. Then, in chapter three, he introduces solitary wave solutions of the Korteweg–de Vries equation … Part two deals with higher dimensional nonlinear theories. … Part three focuses mainly on the solitons in three spatial dimensions. … Based on the author's lecture notes for a graduate-level course, this book is addressed at graduate students in theoretical physics and mathematics, as well as researchers interested in solitons.'
