前言

I have been teaching the course Advanced Quantum Mechanics to graduate studentsat Huazhong Normal University since 1984. Using various textbooks published insideand/or outside China as references, I was able to assemble together a few topics, suchas coherent state, WKB approximation, wave-packet scattering. Lippmann-Schwingerequation, etc for the graduate course that were not already covered by the undergrad-uate Quantum Mechanics course. The idea of writing a new book first emerged in2003 under the encouragement of my students, especially Ms. Xiaoyan Lin. A firstversion of this book appeared in 2004 and was printed for the graduate course touse. From then on the book was revised and printed every year for the course. Afterseveral teaching-revision cycles, it is now ready for publication.Advanced quantum mechanics is a basic course for the graduate students whoplan to specialize in various fields of physics, e.g. theoretical physics, high energyphysics, nuclear physics, condensed matter physics, atomic and molecular physics,optics, astrophysics, etc. Taking this diversity of specialities into account, in addi-tion to constructing a strict scientific framework for quantum mechanics, the presentmanuscript covers a comparatively wide range of topics.Starting from the experimentally observed wave-particle duality of microscopicsystem, the Hilbert space is introduced naturally. With the exception of the basicprinciples of quantum mechanics, no other assumption or "principle" is representeddirectly and simply by writing. In particular, the physical quantities, such as momen-tum, angular momentum, are not given through writing out manually their operatorsin some special representation, e.g. coordinate representation, but are defined throughtheir commutators, starting from their fundamental property of being generators ofcontinuous space transformation. The "uncertainty principle", "Pauli incompatibilityprinciple" are no longer principles, but are derivable theorems in quantum mechanics.There are already quite a number of textbooks for advanced quantum mechanicsavailable. What is the peculiarity of this book that makes it worthy of publication？We have the following considerations.
