Symplectic Geometry and Quantum Mechanics: Operator Theory: Advances and Applications, cartea 166

Autor Maurice A. de Gosson
en Limba Engleză Hardback – 18 mai 2006

Destinat nivelului de cercetare (doctorat și referință profesională), volumul de față reprezintă o sinteză riguroasă a procesului de „symplectizare” a fizicii, fenomen început în anii '70. Găsim în această carte o demonstrație clară a faptului că geometria symplectică nu este doar un instrument pentru mecanica clasică hamiltoniană, ci limbajul natural al mecanicii cuantice. Maurice A. de Gosson alege să lucreze aproape exclusiv în spațiul symplectic plat, o decizie pedagogică strategică ce permite cititorului să pătrundă în esența fenomenelor fără a fi blocat de formalismul excesiv al notațiilor intrinseci.

Structura volumului reflectă o progresie logică de la fundamentele geometriei symplectice și planelor lagrangiene către aplicații complexe în mecanica cuantică în spațiul fazelor. Observăm o atenție deosebită acordată indicilor de intersecție, grupului metaplectic și calculului Weyl, elemente esențiale pentru înțelegerea cuantificării. Comparativ cu lucrarea sa Born-Jordan Quantization, unde autorul se concentra pe echivalența tablourilor Schrödinger și Heisenberg, aici perspectiva este mai largă, integrând topologia symplectică în studiul operatorilor de densitate.

Acoperă aceeași arie tematică ca Symplectic Techniques in Physics de Victor Guillemin, dar Symplectic Geometry and Quantum Mechanics se diferențiază printr-o abordare mai tehnică, axată pe teoria operatorilor, servind drept punte către texte avansate de topologie. În timp ce Structure of Dynamical Systems de J.M. Souriau rămâne un text clasic de geometrizare a fizicii, volumul lui de Gosson este mai ancorat în tehnicile moderne de spațiu al fazelor, oferind clarificări necesare asupra unor subiecte precum principiul incertitudinii, tratat aici dintr-o perspectivă geometrică inedită.

Descriere scurtă

Introduction We have been experiencing since the 1970s a process of “symplectization” of S- ence especially since it has been realized that symplectic geometry is the natural language of both classical mechanics in its Hamiltonian formulation, and of its re?nement,quantum mechanics. The purposeof this bookis to providecorema- rial in the symplectic treatment of quantum mechanics, in both its semi-classical and in its “full-blown” operator-theoretical formulation, with a special emphasis on so-called phase-space techniques. It is also intended to be a work of reference for the reading of more advanced texts in the rapidly expanding areas of sympl- tic geometry and topology, where the prerequisites are too often assumed to be “well-known”bythe reader. Thisbookwillthereforebeusefulforbothpurema- ematicians and mathematical physicists. My dearest wish is that the somewhat novel presentation of some well-established topics (for example the uncertainty principle and Schrod ¨ inger’s equation) will perhaps shed some new light on the fascinating subject of quantization and may open new perspectives for future - terdisciplinary research. I have tried to present a balanced account of topics playing a central role in the “symplectization of quantum mechanics” but of course this book in great part represents my own tastes. Some important topics are lacking (or are only alluded to): for instance Kirillov theory, coadjoint orbits, or spectral theory. We will moreover almost exclusively be working in ?at symplectic space: the slight loss in generality is, from my point of view, compensated by the fact that simple things are not hidden behind complicated “intrinsic” notation.

Recenzii

From the reviews:
"De Gosson’s book is an exhaustive and clear description of almost all the more recent results obtained in connected areas of research like symplectiv geometry, the combinatorial theory of the Maslov index, the theory of the metaplectic group and so on. It fills an important niche in the literature." -Mircea Crâsmareanu, Analele Stiintifice
"This book concerns certain aspects of symplectic geometry and their application to quantum mechanics. … This book seems best suited to someone who already has a solid background in quantum theory and wants to learn more about the symplectic geometric techniques used in quantization. … the book contains useful information about various important topics." (Brian C. Hall, Mathematical Reviews, Issue 2007 e)
“This book covers … symplectic geometry and their applications in quantum mechanics with an emphasis on phase space methods. … The exposition is very detailed and complete proofs are given. … the book takes a particularly fresh point of view on some of the topics and contains a lot of useful information for readers with some background in quantum theory and an interest in the use of symplectic techniques.” (R. Steinbauer, Monatshefte für Mathematik, Vol. 155 (1), September, 2008)

Textul de pe ultima copertă

This book is devoted to a rather complete discussion of techniques and topics intervening in the mathematical treatment of quantum and semi-classical mechanics. It starts with a  rigorous presentation of the basics of symplectic geometry and of its multiply-oriented extension. Further chapters concentrate on Lagrangian manifolds, Weyl operators and the Wigner-Moyal transform as well as on metaplectic groups and Maslov indices. Thus the keys for the mathematical description of quantum mechanics in phase space are discussed. They are followed by a rigorous geometrical treatment of the uncertainty principle. Then Hilbert-Schmidt and trace-class operators are exposed in order to treat density matrices. In the last chapter the Weyl pseudo-differential calculus is extended to phase space in order to derive a Schrödinger equation in phase space whose solutions are related to those of the usual Schrödinger equation by a wave-packet transform.
The text is essentially self-contained and can be used as basis for graduate courses. Many topics are of genuine interest for pure mathematicians working in geometry and topology.
