As we humans have expanded our horizons to see things vastly smaller, faster, larger, and farther than ever before, we have been forced to confront preconceptions born of the human experience and create wholly new ways of looking at the world around us. The theories of relativity and quantum physics were developed out of this need and have provided us with phenomenal, mind-twisting insights into the strange and exciting reality show of our universe. Relativity and Quantum Physics For Beginners is an entertaining and accessible introduction to the bizarre concepts that fueled the scientific revolution of the 20th century and led to amazing advances in our understanding of the universe.

This book is a revised and updated version of Introductory Quantum Physics and Relativity. Based on lectures given as part of the undergraduate degree programme at the University of Leeds, it has been extended in line with recent developments in the field. The book contains all the material required for quantum physics and relativity in the first three years of a traditional physics degree, in addition to more interesting and up-to-date extensions and applications which include quantum field theory, entanglement, and quantum information science. The second edition is unique as an undergraduate textbook as it combines quantum physics and relativity at an introductory level. It expounds the foundations of these two subjects in detail, but also illustrates how they can be combined. It discusses recent applications, but also exposes undergraduates to cutting-edge research topics, such as laser cooling, Bose-Einstein condensation, tunneling microscopes, lasers, nonlocality, and quantum teleportation. Contents: Introduction Old Quantum Theory Quantum Mechanics Applications of Quantum Mechanics Schrödinger Equation in Three Dimensions Spin and Statistics Atoms, Molecules and Lasers Formal Structure of Quantum Mechanics Second Revolution: Relativity Fine Structure of the Hydrogen Atom Relativistic Quantum Mechanics Quantum Entanglement Solutions Readership: Students taking undergraduate-level courses in quantum physics and relativity. Keywords: Quantum Physics;RelativityReview: Key Features: Combines Quantum Physics and Relativity. Covers the two subjects in a more coherent way than existing books. Many universities teach quantum physics and relativity together as one lecture course and so a book that covers both but also shows how they can be combined is a valuable resource Modern Choice of Topics. We will draw on topics from our own research to bring the two subjects up to date and give students a taste of cutting edge research. Examples will include such things as laser cooling, Bose condensation, tunneling microscopes, lasers, Bell's inequalities, quantum teleportation Has questions and answers -- ideal for self-study. This is pitched at typical exam level and so will be excellent for exam practice

Quantum physics and special relativity theory were two of the greatest breakthroughs in physics during the twentieth century and contributed to paradigm shifts in physics. This book combines these two discoveries to provide a complete description of the fundamentals of relativistic quantum physics, guiding the reader effortlessly from relativistic quantum mechanics to basic quantum field theory. The book gives a thorough and detailed treatment of the subject, beginning with the classification of particles, the Klein–Gordon equation and the Dirac equation. It then moves on to the canonical quantization procedure of the Klein–Gordon, Dirac and electromagnetic fields. Classical Yang–Mills theory, the LSZ formalism, perturbation theory, elementary processes in QED are introduced, and regularization, renormalization and radiative corrections are explored. With exercises scattered through the text and problems at the end of most chapters, the book is ideal for advanced undergraduate and graduate students in theoretical physics.

This graduate text introduces relativistic quantum theory, emphasising its important applications in condensed matter physics. Basic theory, including special relativity, angular momentum and particles of spin zero are first reprised. The text then goes on to discuss the Dirac equation, symmetries and operators, and free particles. Physical consequences of solutions including hole theory and Klein's paradox are considered. Several model problems are solved. Important applications of quantum theory to condensed matter physics then follow. Relevant theory for the one electron atom is explored. The theory is then developed to describe the quantum mechanics of many electron systems, including Hartree-Fock and density functional methods. Scattering theory, band structures, magneto-optical effects and superconductivity are among other significant topics discussed. Many exercises and an extensive reference list are included. This clear account of relativistic quantum theory will be valuable to graduate students and researchers working in condensed matter physics and quantum physics.

Hundert schmale Seiten reichen, um die Physik der Moderne zu erklären Wo kommen wir her? Was können wir wissen? Seit ihren umwälzenden Entdeckungen im zwanzigsten Jahrhundert spüren Physiker den Kräften und Teilchen nach, die die Welt im Innersten und Äußersten zusammenhalten. Für jedermann verständlich, hat Carlo Rovelli dieses zauberhafte Buch darüber geschrieben. Es stürmte in wenigen Wochen an die Spitze der italienischen Bestsellerliste und wird derzeit in fast zwanzig Sprachen übersetzt. In eleganten, klaren Sätzen erklärt Rovelli die Physik der Moderne: Einstein und die Relativitätstheorie, Max Planck und die Quantenmechanik, die Entstehung des Universums, Schwarze Löcher, die Elementarteilchen, die Beschaffenheit von Raum und Zeit – und die Loop-Theorie, sein ureigenstes Arbeitsfeld. Ein Buch, das jeder verstehen kann – ein Lesevergnügen zum Staunen, Genießen und Mitreden können. «Von Natur aus wollen wir immer mehr wissen und immer weiter lernen. Unser Wissen über die Welt wächst. Uns treibt der Drang nach Erkenntnis und lernend stoßen wir an Grenzen. In den tiefsten Tiefen des Raumgewebes, im Ursprung des Kosmos, im Wesen der Zeit, im Schicksal der Schwarzen Löcher und im Funktionieren unseres eigenen Denkens. Hier, an den Grenzen unseres Wissens, wo sich das Meer unseres Nichtwissens vor uns auftut, leuchten das Geheimnis der Welt, die Schönheit der Welt, und es verschlägt uns den Atem.», schreibt Carlo Rovelli.

- 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.

Written for non-specialists, this book discusses the apparent conflict between relativity and quantum mechanics. The author proposes a resolution based on a causal interpretation introduced by Louis deBroglie and elaborated by David Bohm. He shows that a "medium" or "aether" may be introduced in a manner consistent with both relativity and quantum theory, and which allows the two theories to be unified via the identification of circularly causal processes at their core. While several crucial experiments are discussed in detail, the mathematics is kept simple, making the discussion accessible to a wide audience.

This book provides a description of the evolution of the concepts of causality and time through modern physics considering first relativity theories and them quantum mechanics. Relativity, at least in the form given by Einstein, denies reality of past, present and future and does not indicate a time direction. On the other hand a time direction is indicated by all the phenomena we observe including our own existence. Quantum mechanics seems to indicate a different story. It is argued that, because of its non deterministic character, it is capable to indicate an objective time direction. This occurs through the phenomena of wave function collapse and entanglement which are discussed at length.
