This textbook fills the gap between the very basic and the highly advanced volumes that are widely available on the subject.

Following the approach of Lev Landau and Evgenii Lifshitz, this book introduces the theory of special and general relativity with the Lagrangian formalism and the principle of least action.

This textbook introduces the numerical techniques required to tackle problems in quantum mechanics, providing numerous examples en route.

This book provides an introduction into the fundamentals of non-relativistic quantum mechanics. The second of a two-volume reference, it discusses applications and extensions to more complex problems. Includes exercises and problems with solutions.

This book provides an introduction into the fundamentals of non-relativistic quantum mechanics. The first part of a two-volume reference, it develops essential principles and supports learning with exercises and problems with solutions.
