Quantum Mechanics and Electrodynamics

This book highlights the power and elegance of algebraic methods of solving problems in quantum mechanics. It shows that symmetries not only provide elegant solutions to problems that can be solved exactly, but also substantially simplify problems that must be solved approximately.

Furthermore, the book provides an elementary exposition of quantum electrodynamics and its application to low-energy physics, along with a thorough analysis of the role of relativistic, magnetic, and quantum electrodynamic effects in atomic spectroscopy. Included are essential derivations made clear through detailed, transparent calculations.

The book's commitment to deriving advanced results with elementary techniques, as well as its inclusion of exercises will enamor it to advanced undergraduate and graduate students.

Aceasta carte evidentiaza puterea si eleganta metodelor algebrice de rezolvare a problemelor in mecanica cuantica. Aceasta arata ca simetriile nu numai ca ofera solutii elegante la problemele care pot fi rezolvate exact, ci simplifica substantial problemele care trebuie rezolvate aproximativ. o analiza aprofundata a rolului efectelor electrodinamice relativiste, magnetice si cuantice in spectroscopia atomica.
