Relativistic Quantum Mechanics (Paperback, 2011 ed.): Armin Wachter Relativistic Quantum Mechanics (Paperback, 2011 ed.)

R3,810 Discovery Miles 38 100 Ships in 10 - 15 working days

* Which problems do arise within relativistic enhancements of the Schrodinger 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."

Relativistische Quantenmechanik (German, Paperback, 2005 ed.): Armin Wachter Relativistische Quantenmechanik (German, Paperback, 2005 ed.)
Armin Wachter
R1,346 Discovery Miles 13 460 Ships in 10 - 15 working days

- Welche Probleme tauchen in relativistischen Erweiterungen der Schrodinger-Theorie auf, insbesondere wenn man an der gewohnten Ein-Teilchen-Wahrscheinlichkeitsinterpretation festhalt?

- Inwieweit konnen diese Schwierigkeiten uberwunden werden?

- Worin besteht die physikalische Notwendigkeit von Quantenfeldtheorien?

Viele Bucher geben auf solch fundamentale Verstandnisfragen nur unzureichend Antwort, indem sie das relativistisch-quantenmechanische Ein-Teilchenkonzept zugunsten einer moglichst fruhen Einfuhrung 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 verstandliche Weise die Notwendigkeit quantisierter Felder. Die ersten beiden Kapitel beschaftigen sich mit der ausfuhrlichen Darlegung und Gegenuberstellung 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 Begrundung nicht herumkommt.

Dieses Lehrbuch wendet sich an alle Studierenden der Physik, die an einer ubersichtlich geordneten Darstellung der relativistischen Quantenmechanik im engeren Sinne und deren Abgrenzung zu Quantenfeldtheorien interessiert sind.

Repetitorium Theoretische Physik (German, Paperback, 2., uberarb. Aufl. 2005): Armin Wachter Repetitorium Theoretische Physik (German, Paperback, 2., uberarb. Aufl. 2005)

R2,237 Discovery Miles 22 370 Ships in 10 - 15 working days

Die uberarbeitete und aktualisierte zweite Auflage des Repetitorium Theoretische Physik enthalt den kanonischen Lehrstoff der Theoretischen Physik, der in den ersten 6 Semestern an deutschen Universitaten gelehrt wird. Zwei junge theoretische Physiker bieten den Prufungsstoff fur Vordiplom, Zwischenprufung, Diplom und Staatsexamen in pragnanter und argumentativ stringenter Darstellung. Von der klassischen Mechanik uber Elektrodynamik, Quantenmechanik und Statistische Physik/Thermodynamik werden alle Themen in einer axiomatisch-deduktiven Darstellung behandelt und durch UEbungen mit Loesungen sowie Zusammenfassungen gefestigt. Das Buch eignet sich sowohl als begleitendes Lehrbuch als auch zum Wiederholen und Strukturieren von bereits vertrautem Lehrstoff und uberbruckt somit die Kluft zwischen umfangreichen Lehrbuchern und reinen Formelsammlungen. Dieses Repetitorium der Theoretischen Physik wird insbesondere all jene begeistern, die sich in der Prufungsvorbereitung befinden und den Lehrstoff noch einmal im Zusammenhang durchgehen wollen.
