The Formulation of the Kohn-Hulthén Variational Principle in Terms of the Scattering Operation Formalism (Classic Reprint)

Explore a rigorous approach to quantum scattering with a new formulation of a classic principle.

This book presents the Kohn–Hulthén variational principle in the H-representation, offering a computable framework for scattering amplitudes. This edition explains how to frame scattering problems with a complete set of commuting variables, introduces the concept of representers in the H-representation, and develops the variational procedure using functional A(T). It aims to make the mathematics more approachable by using Green’s functions that are simpler to handle in this representation, while staying true to the underlying physics.

• Learn how to construct and use the H-representation for scattering problems.
• Understand the variational principle and its practical implications for computing amplitudes.
• See how to formulate and solve integral equations that arise in this framework.
• Explore the relationship between the scattering operator and its kernel in the H-representation.
