Quantum Mechanics 3rd Edition

Excellent customer service

The book is really what I wanted. And its is very cheap. It costs me only 12 USD. Really good!

Despite being listed as hardcover, this is the paperback version of the book and checking the ISBN on the publisher's site confirms this. I only did so, however, after speaking to customer service and receiving two replacements which were also paperback. So if you order this book, do not expect a hardcover copy. I don't think there is a hardcover version of this book currently in print. So be aware of this if it matters to you.

It is completely new, I really got surprised!

One very very thick book!Merzbacher's Quantum Mechanics is not the most popular graduate text for QM; however, it is one of the options that some professors will choose.This text tries to be a very thorough study of quantum mechanics, but at times it is definitely very difficult to follow. Let's say we're looking to study topic A, and you turn to the index to look for it. You'll most likely find it in several different chapters, linked to different topics.The book also doesn't give enough information for you to solve the problems inside, maybe this is just because I am just not bright enough though...Nonetheless, it would be worthwhile to buy this book if you're taking a class that requests it. It's very difficult to navigate the book in an electronic form.Happy shopping! :>

Not surprisingly, the enthusiasm with which I support this graduate-level text (I refer to the second edition) is hardly shared by a majority of reviewers. However, read the review in Physics Today: "notable for making contents accessible to the average student, new ideas are exposed via very simple mathematics and thus presented in a simple way." (1971, Volume 24, Number 6). That review is less enthusiastic than mine, however ! Peruse articles written by Eugen Merzbacher in American Journal of Physics, there absorb his teaching style. Background of Eugen Merzbacher:(A) "Two of his articles on quantum mechanics formalism were deemed by readers to be among the fifty most important published by the American Journal of Physics in its first 50 years."(B) The American Association of Physics Teachers presented him with Oersted Medal in 1992 (read: AJP, Volume 60).While much of the material in this text is standard, much is also unique, both in viewpoint and execution:(1) The manner in which the imaginary unit is brought forth in chapter one offers a different perspective (compare Merzbacher to Schiff's derivation).(2) Turn to chapter eight: basic principles of wave mechanics), as lucid as one finds elsewhere (compare Schiff).(3) The interspersed student exercises are effective for imparting simple manipulative skill. Few are beyond the reach of an average student. Merzbacher writes: "these exercises supplement the main text." Additional problems, end of chapter problems, are extensions of the main text and require more work.(4) Scattering Theory: Merzbacher excels here (as to be expected, as this is a portion of his research specialty). Exercise #11.1 is useful in this regard, a numerical exercise associated with wave packets (second edition, page 221). Green's functions are introduced in the span of five pages and utilized throughout chapter eleven. Parabolic coordinatesfor Coulomb potential lucidly presented (again, compare to Schiff ).(5) Next up, spin. A nugget of wisdom (often downplayed): "....unless the electron, moving in the field of the nucleus, possesses intrinsic angular momentum, conservation of angular momentum can not be maintained for an isolated system such as an atom..." This chapter is preparation for the dynamics of two-level- systems and another nugget of wisdom: "...in practical terms the experimental arrangement usually tells us unambiguously when the homogeneous ensemble of a correlated state may to a very high degree of approximation be replaced by a suitably weighted mixture of its components (page 293, second edition).(6) Fourteenth Chapter: Linear Vector Spaces, introduction to the Dirac bra and ket formalism. Nowadays, it is usual to find this material located earlier, however, the placement here follows Merzbacher's logical progression. One notes that Shankar's excellent text places the material in chapter one. In contrast, Merzbacher "builds" up to the material.(7) Correspondence Principle: "...it does not give us an unambiguous prescription of how to construct the quantum version of any given classical theory." (page 338). Also: "there are unitary transformations which have no classical analog." (page 345). Next, the algebra of raising and lowering operators for harmonic oscillator is presented.(8) Rotations and Symmetry: A tour de force (Of that topic I possess a copy of class notes from the author's lectures).(9) Merzbacher writes that his final chapters (19-24) are referred to as Advanced Quantum Mechanics: a preview of quantum electrodynamics, high-energy particles, many-body theory (compare Sakurai). A satisfying conclusion to a fine graduate-level textbook. Reiterating: complete the exercises as they occur in the text (this instills confidence and alerts one to upcoming harder problems, those at the end of chapter). Hints are often provided. Before continuing to the following section of any portion of this text, complete the exercises !(10) Prerequisites: " ... earlier exposure to quantum concepts, course in classical mechanics and electromagnetism," not to mention the mathematics which one is presumed to have already assimilated (Mary Boas, Mathematical Methods). The homage to his teacher, Julian Schwinger, is apparent in his methodology for treating angular momentum.Are there easier graduate-level texts ? Perhaps. Certainly, there are less densely worded texts, but, consider spending some time perusing one of the great teaching books by a great teacher.

Hi, This book is very poor in helping students trying to solve its problems. The problems are such a great extension of what is covered in each chapter, I'm not even sure if most professors could completely solve its problems. I am looking for a legal solution manual to this book. I will pay top dollar for it.

good
