Time in Quantum Mechanics [Paperback]

The treatment of time in quantum mechanics is still an important and challenging open question in the foundation of the quantum theory.

This multi-authored book, written as an introductory guide for newcomers to the subject, as well as a useful source of information for the expert, covers many of the open questions. The book describes the problems, and the attempts and achievements in defining, formalizing and measuring different time quantities in quantum theory.

Characteristic Times in One-Dimensional Scattering.- The TimeEnergy Uncertainty Relation.- Jump Time and Passage Time: The Duration ofs a Quantum Transition.- Bohm Trajectory Approach to Timing Electrons.- Decoherent Histories for SpaceTime Domains.- Quantum Traversal Time, Path Integrals and Superluminal Tunnelling.- Quantum Clocks and Stopwatches.- The Local Larmor Clock, Partial Densities of States, and Mesoscopic Physics.- Standard QuantumMechanical Approach to Times of Arrival.- Experimental Issues in QuantumMechanical Time Measurement.- Microwave Experiments on Tunneling Time.- The Two-State Vector Formalism: An Updated Review.

The treatment of time in quantum mechanics is still an important and challenging open question in the foundation of the quantum theory. This book describes the problems, and the attempts and achievements in defining, formalizing and measuring different time quantities in quantum theory, such as the parametric (clock) time, tunneling times, decay times, dwell times, delay times, arrival times or jump times. This multi-authored book, written as an introductory guide for newcomers to the subject, as well as a useful source of information for the expert, covers many of the open questions. After the brief historical overview in the introduction, 12 contributions are devoted to conceptual and theoretical investigations as well as experimental issues in quantum-mechanical time measurements.
