About this title

Synopsis

Uncover how Green's functions bridge many-body theory and the Thomas-Fermi model, starting from Hartree-Fock and moving to corrections that include exchange and inhomogeneity.

This work presents a systematic derivation that starts from the quantum many-body equations and shows how the Thomas-Fermi density appears as the leading term. It uses the Green's function formalism to connect ground-state properties with a practical, mixed position-momentum representation, and it discusses how higher-order corrections can be generated and interpreted. The discussion keeps the focus on core ideas while outlining how correlation effects might be included in future extensions.

See how the Hartree-Fock approximation arises from the antisymmetric product of one-particle Green's functions.
Learn how the zeroth-order term yields the Thomas-Fermi density and how the density is recovered from Green's functions.
Understand how exchange and inhomogeneity effects appear together in the first non-vanishing correction to the Thomas-Fermi model.
Explore the role of the mixed representation and the infinite-order differential operator that connects the Green's function to the original equations.

Ideal for readers of quantum many-body theory, atomic structure, and theoretical physics who want a clear path from a foundational model to its quantum corrections.

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.
