Dieses Buch richtet sich an Studierende der Physik, die bereits über Grundkenntnisse der Quantenmechanik verfügen und relativistische Wellengleichungen kennenlernen möchten. Im Hauptteil des Buchs behandelt der Autor die Klein-Gordon-Gleichung und die Dirac-Gleichung, wobei er deren Bedeutung hervorhebt und auf interessante Anwendungen eingeht. Daneben wird die historische Entwicklung der Gleichungen thematisiert eine Verbindung zur Galilei-invarianten nicht-relativistischen Quantenmechanik hergestellt. Zuletzt werden kurz die Grundzüge der Quantenelektrodynamik und Elemente der relativistischen Streutheorie erläutert. Anhand von Aufgaben werden die Leser dazu motiviert, den Stoff selbst beispielhaft nachzurechnen.

* Which problems do arise within relativistic enhancements of the Schrödinger theory, especially if one adheres to the usual one-particle interpretation? * To what extent can these problems be overcome? * What is the physical necessity of quantum field theories? In many textbooks, only insufficient answers to these fundamental questions are provided by treating the relativistic quantum mechanical one-particle concept very superficially and instead introducing field quantization as soon as possible. By contrast, this book emphasizes particularly this point of view (relativistic quantum mechanics in the ''narrow sense''): it extensively discusses the relativistic one-particle view and reveals its problems and limitations, therefore illustrating the necessity of quantized fields in a physically comprehensible way. The first two chapters contain a detailed presentation and comparison of the Klein-Gordon and Dirac theory, always with a view to the non-relativistic theory. In the third chapter, we consider relativistic scattering processes and develop the Feynman rules from propagator techniques. This is where the indispensability of quantum field theory reasoning becomes apparent and basic quantum field theory concepts are introduced. This textbook addresses undergraduate and graduate Physics students who are interested in a clearly arranged and structured presentation of relativistic quantum mechanics in the "narrow sense" and its connection to quantum field theories. Each section contains a short summary and exercises with solutions. A mathematical appendix rounds out this excellent textbook on relativistic quantum mechanics.

- Welche Probleme tauchen in relativistischen Erweiterungen der Schrödinger-Theorie auf, insbesondere wenn man an der gewohnten Ein-Teilchen-Wahrscheinlichkeitsinterpretation festhält? - Inwieweit können diese Schwierigkeiten überwunden werden? - Worin besteht die physikalische Notwendigkeit von Quantenfeldtheorien? Viele Bücher geben auf solch fundamentale Verständnisfragen nur unzureichend Antwort, indem sie das relativistisch-quantenmechanische Ein-Teilchenkonzept zugunsten einer möglichst frühen Einführung der Feldquantisierung relativ schnell abhandeln oder ganz weglassen. Im Gegensatz dazu betont das vorliegende Lehrbuch gerade diesen Ein-Teilchenaspekt (relativistische Quantenmechanik ‚im engeren Sinne’), diskutiert die damit einhergehenden Probleme und motiviert somit auf physikalisch verständliche Weise die Notwendigkeit quantisierter Felder. Die ersten beiden Kapitel beschäftigen sich mit der ausführlichen Darlegung und Gegenüberstellung der Klein-Gordon- und Dirac-Theorie - immer mit Blick auf die nichtrelativistische Theorie. Im dritten Kapitel werden relativistische Streuprozesse behandelt und die Feynman-Regeln aus Propagatorverfahren heraus entwickelt. Dabei wird auch hier deutlich, warum man letztlich um eine quantenfeldtheoretische Begründung nicht herumkommt. Dieses Lehrbuch wendet sich an alle Studierenden der Physik, die an einer übersichtlich geordneten Darstellung der relativistischen Quantenmechanik ‚im engeren Sinne’ und deren Abgrenzung zu Quantenfeldtheorien interessiert sind.

Relativistic Quantum Mechanics - Wave Equations concentrates mainly on the wave equations for spin-0 and spin-1/2 particles. Chapter 1 deals with the Klein-Gordon equation and its properties and applications. The chapters that follow introduce the Dirac equation, investigate its covariance properties and present various approaches to obtaining solutions. Numerous applications are discussed in detail, including the two-center Dirac equation, hole theory, CPT symmetry, Klein's paradox, and relativistic symmetry principles. Chapter 15 presents the relativistic wave equations for higher spin (Proca, Rarita-Schwinger, and Bargmann-Wigner). The extensive presentation of the mathematical tools and the 62 worked examples and problems make this a unique text for an advanced quantum mechanics course.
