Which is the best book for quantum physics?

  1. Sep 2, 2016 #1
    In our BS Hons course, we stumbled upon quantum physics. This aforementioned topic is, if not, completely new to me. Therefore, for a better understanding and easy to understand book is necessary; not compromising on the mathematical side though.

    What do you mean with this? If I read this, I would immediately think of a book that goes into C*-algebras, functional analysis and rigged Hilbert spaces. None of this is "easy to understand". So you need to be very careful and very precise in what you want.

    I meant a book which is written in clear , straightforward English... That would enable me to comprehend easily the postulates and theories along with the Mathematics..

    1. Perhaps start with some history to see te need for the theory? The most simple but basic: Polkinghorne: quantum theory, a very short introduction (5 Hours read if you're into some physics)
    2. Gary Bowman: Essential quantum mechanics. Starts you off with the postulates and learns you formalism and bra-ket in no-time.
    3. Dirac: The principes of quantum mechanics (if you can't get enough)
    Btw: Polkinghorne was a student of Dirac.

    A Modern Approach to Quantum Mechanics by Townsend is pretty good. I've heard it described as an undergrad-Sakurai, but I admit I've never used Sakurai.

    I am assuming you already know calculus including differential equations.

    1. You need a good foundation of linear Algebra from something like
    Linear Algebra as an Introduction to Abstract Mathematics by Schilling

    If you can do without a printed copy, the book is available for free here

    Pick any decent linear algebra book that does not skimp on vector spaces.

    2. Read susskind to get a decent, modern, but not too rigorous overview

    Here are the matching video lectures.

    3. Read McIntyre to get an excellent first course that uses the spins-first approach

    In my opinion the spins first approach is the easiest and yet most modern way to learn Quantum mechanics.

    The Townsend and Sakurai books mentioned above use the same approach. I like McIntyre the best though. But any of the three will do.

    The Bowman book mentioned above, although does not use a spins first approach strictly, is also a very good and short introduction.

    1. OK. 2. Very good!. 3. Dirac's book is a very tough read (almost like reading von Neumann's book), so I would go for a more modern writing. Sakurai's text is lucid and up to the point without too fancy mathematics and is definitely inspired from Dirac's book but with a modern notation.

    I highly recommend Shankar's QM(1) Book, it undergraduate/beginning graduate level, starts off with a chapter on the linear algebra that you need ( using Dirac's bra-ket notation), and then after a quick review of classical mechanics, proceeds to build the theory from the 'postulates' of Quantum mechanics. It has everything you need for a first course in quantum mechanics, and more, such as two chapters on path integrals and a chapter on Dirac equation, moreover, there are solutions to selected exercises at the end.
    A book that goes well with Shankar's QM is Zettilli's QM book(2), it has a lot of solved problems and many problems at the end of each chapter to solidify your understanding of the subject matter.
