The Quantum Mechanics Solver 1 uniquely illustrates the application of quantum mechanical concepts to various fields of modern physics. It aims at encouraging the reader to apply quantum mechanics to research problems in fields such as molecular physics, condensed matter physics or laser physics. Advanced undergraduates and graduate students will find a rich and challenging source of material for further exploration. This book consists of a series of problems concerning present-day experimental or theoretical questions on quantum mechanics | Jean-Louis Basdevant Jean Dalibard The Quantum Mechanics Solver How to Apply Quantum Theory to Modern Physics Second Edition With 59 Figures Numerous Problems and Solutions ASpringer Professor Jean-Louis Basdevant Department of Physics Laboratoire Leprince-Ringuet Ecole Polytechnique 91128 Palaisseau Cedex France E-mail Professor Jean Dalibard Ecole Normale Superieure Laboratoire Kastler Brossel rue Lhomond 24 75231 Paris CX 05 France E-mail Library of Congress Control Number 2005930228 ISBN-10 3-540-27721-8 2nd Edition Springer Berlin Heidelberg New York ISBN-13 978-3-540-27721-7 2nd Edition Springer Berlin Heidelberg New York ISBN-10 3-540-63409-6 1 st Edition Springer Berlin Heidelberg New York ISBN-13 978-3-540-63409-6 1 st Edition Springer Berlin Heidelberg New York This work is subject to copyright.
