Quantum Mechanics: A Modern Development (2Nd Edition) by Leslie E Ballentine | (PDF) Free Download

Description

Although there are many textbooks that deal with the formal apparatus of quantum mechanics (QM) and its application to standard problems, none take into account the developments in the foundations of the subject which have taken place in the last few decades. There are specialized treatises on various aspects of the foundations of QM, but none that integrate those topics with the standard material. This book aims to remove that unfortunate dichotomy, which has divorced the practical aspects of the subject from the interpretation and broader implications of the theory.In this edition a new chapter on quantum information is added. As the topic is still in a state of rapid development, a comprehensive treatment is not feasible. The emphasis is on the fundamental principles and a few key applications. The impact of quantum information theory on the foundations of quantum mechanics is discussed. In addition, there will be minor revisions to several chapters.The book is intended primarily as a graduate level textbook, but it will also be of interest to physicists and philosophers who study the foundations of QM. Parts of it could be used by senior undergraduates too.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐I cannot stress enough how bad I found the second half of Sakurai! This became my go-to quantum book, both for class and studying for the Comps. Ballentine writes very clearly and often points out where other texts can be misleading (ex: “Big Box normalization” for scattering). The problem selection is a little lacking (mostly derivations and not too much in the way of actual problem solving), but I’d still give it 5* for the content, the presentation, and the clear examples presented. Great as a primary, standalone, or supplementary text on quantum mechanics.Please note: The level that this book is written at is about on par with Sakurai; it’s aimed toward graduates. For the undergrad, I recommend starting with Griffiths (who is by no means the most rigorous, but will get you your “sea legs,” as it were). From there you may wish to dive right into Grad quantum with this one, or try Sakurai (I guess it is a classic for a reason).

⭐Ballentine is one of the few quantum physicist that defend the ensemble interpretation of QM so he write this book accordingly. As in the previous edition the author takes its time in explaining why he adopts some postures contrasting this with more orthodox point of views. The new chapter in quantum information is particularly interesting since is the main addition compared to the previous edition I passed directly to it.

⭐Great!

⭐This is an interesting book to read and it is my favourite QM book. The author presents both foundations and applications of QM starting from the basic postulates. It includes standard topics like angular momentum and scattering theory, an introduction to many-particle physics (second quantization) and to the quantization the EM field, as well as a very detailed(!) analysis of EPR like experiments. The treatment of the foundations of the subject is more careful than in most textbooks on QM and the author frequently points out flaws in the arguments presented by other authors. He devotes considerable space to air his “purely statistical” interpretation of QM. I am not sure, however, whether a beginning student is more confused by the rather formal development in the first chapters, or whether a beginner immediately benefits from it. If you are confused, check out the book by Shankar and then come back to Ballentine.The discussion of the standard applications of QM is very lucid and mathematically exhaustive. In this part of the book the author does not refrain from critisizing other textbooks and different interpretations of QM either. The ferocity with which the author does this is sometimes outright hilarious.If a specific topic is covered in this book, I prefer Ballentine’s more thorough treatment almost invariably over other standard textbooks with the only exception being Fermi’s Golden Rule, which is better covered in Cohen-Tannoudji’s book.

⭐First of all, let me say that my review is based upon the first edition of this book. I haven’t seen the 2nd edition, and 2nd editions aren’t always better (e.g., Goldstein’s 2nd edition is a disaster compared to his 1st). Now, for the review: There is only one other book which I consider to be as didactic as this one, which is Shankar’s text. Shankar’s book is more friendly and a better introduction to QM, but Ballentine’s book is a bit more advanced and gives a lot of thought toquestions of interpretation which are seriously neglected in other books, while dealing with some advanced topics: the Wigner-Eckart theorem, BCS theory of superconductivity, etc. . . His presentations are lucid and to the point, and he is also careful to point out all sorts of common errors, which readers might have aquired from other books. Every idea is motivated before being introduced. Examples are provided throughout the text, and answers are given to selected exercises.This book seems to me to truly teach, and is superior to Sakurai, Landau, Messiah and a host of others, which all have some major flaw or another. It’s worth its price […]

⭐I am using this book as a supplimentary text for a 1st-year graduate course in quantum mechanics (the other text is Sakurai). I find the book extremely clear and well organized. In many ways, I like it more than Sakurai. For instance, many modern ideas are developed in detail – for instance Bell’s inequality and related topics – but, as well, the more standard topics are also discussed thoroughly. Many references to original literature included. Good problems too.

⭐Nível altíssimo, tem tudo que se precisa em um curso de mecânica quântica básica de pós graduação.Do not buy the kindle version before you have checked the sample on your device! Most of the formulas (not the inline formulas) but the ones in the middle with their own reference, have very bad graphical quality. I hope the editor or whoever does the digitization of the book can solve this asap, otherwise the ebook is really unusable.
