9789971507817: Trajectories and Rays

Synopsis

This book presents selected topics about the path-integral method in Quantum Mechanics and Optics. Starting from an introduction to the grounds of functional integration theory, the main arguments of quantum and statistical mechanics, where the path-integral method works, are exposed. In particular, the partition function, the concept of instanton, tunneling and dissipative phenomena are analysed. The final section is devoted to selected and solved problems. This volume will be useful to beginners as well as more advanced students and researchers in the field.

Synopsis

Drawing from presentations at a number of workshops, seminars, and conferences, covers selected topics in optics and tunneling, and their applications in contexts where the interaction of systems with few degrees of freedom with a thermal bath become important, such as statistical mechanics, condensed matter, and polymer, nonlinear, and energy phys
