Lectures on Quantum Mechanics: Simple Systems. This first volume covers about the same material as the first 2 chapters of Sakurai's Modern Quantum Mechanics.

Lectures on Quantum Mechanics: Simple Systems. Berthold-Geor. ardcover. Englert's books seem to follow Schwinger fairly closely, though Schwinger's measurement symbols aren't used. Englert seems to have put some thought into actually teaching with this approach, which he's simplified, but not dumbed down. 5 people found this helpful.

Note: The three volumes are not sequential but rather independent of each other and largely self-contained.Basic Matters is a first introduction to quantum mechanics that does not assume any prior knowledge of the subject. The emphasis is on the general structure as the necessary foundation of any understanding. Starting from the simplest quantum phenomenon, the Stern-Gerlach experiment with its choice between two discrete outcomes, and ending with one-dimensional continuous systems, the physical concepts and notions as well as the mathematical formalism of quantum mechanics are developed in successive, manageable steps. The presentation is modern inasmuch as the natural language of the trade - Dirac's kets and bras and so on - is introduced early, and the temporal evolution is dealt with in a picture-free manner, with Schrodinger's and Heisenberg's equations of motion side by side and on equal footing.The reader of Simple Systems is not expected to be familiar with the material in Basic Matters, but should have the minimal knowledge of a standard brief introduction to quantum mechanics with its typical emphasis on one-dimensional position wave functions. The step to Dirac's more abstract and much more powerful formalism is taken immediately, followed by reviews of quantum kinematics and quantum dynamics. The important standard examples (force-free motion, constant force, harmonic oscillator, hydrogen-like atoms) are then treated in considerable detail, whereby a nonstandard perspective is offered wherever it is deemed feasible and useful. A final chapter is devoted to approximation methods, from the Hellmann-Feynman theorem to the WKB quantization rule.Perturbed Evolution has a closer link to Simple Systems than that volume has to Basic Matters, but any reader familiar with the subject matter of a solid introduction to quantum mechanics - such as Dirac's formalism of kets and bras, Schrodinger's and Heisenberg's equations of motion, and the standard examples that can be treated exactly, with harmonic oscillators and hydrogen-like atoms among them - can cope with the somewhat advanced material of this volume. The basics of kinematics and dynamics are reviewed at the outset, including discussions of Bohr's principle of complementarity and Schwinger's quantum action principle. The Born series, the Lippmann-Schwinger equation, and Fermi's golden rule are recurring themes in the treatment of the central subject matter - the evolution in the presence of perturbing interactions for which there are no exact solutions as one has them for the standard examples in Simple Systems. The scattering by a localized potential is regarded as a perturbed evolution of a particular kind and is dealt with accordingly. The unique features of the scattering of indistinguishable quantum objects illustrate the nonclassical properties of bosons and fermions and prepare the groundwork for a discussion of multi-electron atoms.

Englert edited Julian Schwinger's posthumous Quantum Mechanics book. Englert's books seem to follow Schwinger fairly closely, though Schwinger's measurement symbols aren't used. Englert seems to have put some thought into actually teaching with this approach, which he's simplified, but not dumbed down.

After a brief chapter explaining why classical determinism must be abandoned at the quantum level, the book uses the example of Stern-Gerlach experiments to develop the mathematics of QM, a very satisfying alternative to the usual Olympian axiomatic approach.

This first volume covers about the same material as the first 2 chapters of Sakurai's Modern Quantum Mechanics.

This and Sakurai are where I learnt my quantum mechanics from. To me there is no other way to learn quantum mechanics. I look to Griffiths with a bit of distaste because I was taught in quantum mechanics in a radically different way and Griffiths, in my mind, is the wrong way. Griffiths an excellent book for a second quantum course but it lacks heavily in the foundational ideas. Englert really picks up the ball here. Right from page one you are doing bra-ket notation and talking about spin-1/2 systems although you don't know it at the time. I prefer this way as you can introduce ideas like Heisenberg picture, Schrödinger picture, unitary evolution, Born rule, higher spin dimension, and the density matrix formulation more naturally.

Given that I love the way this book presents the material, I consider it more a reference then a book to learn from. I find it to be a bit difficult to get used to the notation and I think Sakurai is better here because he has better explanations. However once you have an idea of what you are doing, this book is great. I found myself referencing it again and again when I took a course in advanced quantum theory. I also have to say the treatment of the free particle is incredibly lucid and the best I've seen. I haven't read the other two books but I do own them and have glanced at various parts so I don't know how they compare to this one.

So to sum up, excellent supplement to Sakurai when you are learning the quantum formalism and a great book to keep by your side as you venture forth in quantum mechanics.
