Cover of Operational Quantum Physics
This text offers a systematic presentation of quantum mechanics, making use of the full probabilistic structure of this theory. Accordingly, the notion of an observable as a positive operator valued (POV) measure is explained in great detail, and the ensuing quantum measurement theory is developed and applied both to a resolution of long-standing conceptual and interpretational puzzles in the foundations of quantum mechanics, and to an analysis of various recent fundamental experiments.

Cover of The Quantum Theory of Measurement
The amazing accuracy in verifying quantum effects experimentally has recently renewed interest in quantum mechanical measurement theory. In this book the authors give within the Hilbert space formulation of quantum mechanics a systematic exposition of the quantum theory of measurement. Their approach includes the concepts of unsharp objectification and of nonunitary transformations which are needed for a unifying description of various detailed investigations. The book, which may be regarded as a first step toward a textbook on the problem of measurements, addresses advanced students and researchers in physics and philosophy of science.

Cover of Quantum Electron Liquids and High-Tc Superconductivity
The goal of these courses is to give the non-specialist an introduction to some old and new ideas in the field of strongly correlated systems, in particular the problems posed by the high-Tc superconducting materials. The starting viewpoint to address the problem of strongly correlated fermion systems and related issues of modern condensed matter physics is the renormalization group approach applied to quantum field theory and statistical physics. The authors review the essentials of the Landau Fermi liquid theory, they discuss the 1d electron systems and the Luttinger liquid concept using different techniques. Finally they present the basic phenomenology of the high-Tc compounds and different theoretical models to explain their behaviour.
