"Scientists other than quantum physicists often fail to comprehend the enormity of the conceptual change wrought by quantum theory in our basic conception of the nature of matter," writes Henry Stapp. Stapp is a leading quantum physicist who has given particularly careful thought to the implications of the theory that lies at the heart of modern physics. In this book, which contains several of his key papers as well as new material, he focuses on the problem of consciousness and explains how quantum mechanics allows causally effective conscious thought to be combined in a natural way with...

Operational Quantum Theory II is a distinguished work on quantum theory at an advanced algebraic level. Quantum theory (nonrelativistic quantum mechanics and quantum theory) is developed from a representation theory of lie group and lie algebraic operations acting on both finite and infinite dimensional vector spaces. This book deals with Lorentz Group Embedding and Lorentz Operations, eseigenvalues and invariats for non-compact operations as well as harmonic analysis of noncompact nonabelian Lie groups and their homogenus spaces. Additionally, an attempt is given to understand...

C* tensor categories are a point of contact where Operator Algebras and Quantum Field Theory meet. They are the underlying unifying concept for homomorphisms of (properly infinite) von Neumann algebras and representations of quantum observables.

The present introductory text reviews the basic notions and their cross-relations in different contexts. The focus is on Q-systems that serve as complete invariants, both for subfactors and for extensions of quantum field theory models.

It proceeds with various operations on Q-systems (several decompositions, the mirror Q-system,...

Originaltext und ausfuhrlicher historischer Kommentar von Claus Kiefer

Die Arbeit von Einstein, Podolsky und Rosen (EPR) aus dem Jahr 1935 gehort zu den Klassikern der modernen Physik. In ihr wird zum ersten Mal die zentrale Eigenschaft der Quantentheorie thematisiert: die Verschrankung. Im allgemeinen sind Systeme in der Natur miteinander verschrankt, das heit, sie besitzen nur einen gemeinsamen, nicht aufteilbaren, Zustand. Diese Tatsache ist fur alle Merkwurdigkeiten verantwortlich, die gemeinhin mit der Quantentheorie in Verbindung gebracht werden, wozu die Gedankenexperimente...

After about a century of success, physicists feel the need to probe the limits of validity of special-relativity base theories. This book is the outcome of a special seminar held on this topic. The authors gather in a single volume an extensive collection of introductions and reviews of the various facets involved, and also includes detailed discussion of philosophical and historical aspects.

Die Geheimnisse des Mikrokosmos aufzudecken, hat die Physiker seit Jahrhunderten fasziniert. Doch obwohl in den vergangenen Jahrzehnten viele interessante Entdeckungen gemacht wurden, bleiben noch Fragen offen, die Harald Fritzsch in diesem Buch von der physikalischen und mathematischen Seite beleuchtet:

- Haben die Physiker mit der Standardtheorie der Elementarteilchenphysik schon eine exakte Beschreibung der Teilchenwelt gefunden?
- Gibt es wirklich eine Grosse Vereinigung aller fundamentalen Krafte?
- Und sind die Leptonen, (wie das Elektron), oder die Bausteine der...
