About this title

Synopsis

Explore the core methods of quantum scattering and how different formalisms connect to practical results.

This book introduces the scattering operator formalism and the variational principles that help estimate scattering amplitudes, with a focus on clear, workable approaches for complex problems.

Readers gain a structured path through time-independent and time-dependent pictures, including how variational methods like the Schwinger and Kohn–Hulthen principles can produce reliable approximations. The text also shows how to relate abstract equations to concrete quantities, such as scattering amplitudes and Green’s functions, while highlighting the role of symmetry and reciprocity in scattering theory.

Foundations of the scattering operator formalism and how it yields scattering amplitudes.
Two main variational principles and how they can be used with trial functions for accurate results.
Connections between time-independent and time-dependent viewpoints, with practical implications.
Extensions to systems with internal degrees of freedom and the role of Green’s functions.

Ideal for readers of advanced quantum mechanics and mathematical physics who want a solid, applied treatment of scattering theory and its multiple formalisms.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
