Methods To Study Regular To Chaos Transition In Finite Quantum Systems

This book is a small compilation of a few methods that are used in the area of nonlinear dynamics in physics for studying the chaos presiding at the very quantum level of finite interacting quantum systems. We shall get acquainted with such methods and observe their implications to some random matrix models and some realistic spin-lattice chains. The models that are used here have already studied in the past by many groups and hence we shall not get into much detail.
