Textbooks and other Sources

Quantum mechanics is counter-intuitive. There will be confusing aspects; you will need to invest time and effort to clear up these confusions.

Do not expect to get comfortable with QM unless you do a fair amount of reading and problem-solving.

It is strongly recommended that you work through one or more texts. Working through Prof. Nash's lecture notes is an absolute minimum. It would be a very good idea to read a couple of sections every week.
Additional texts are listed below, and there are links to lecture notes etc. There are many textbooks on introductory quantum mechanics (e.g., carried by the Maynooth library, physically and as e-books). Textbooks have differences in ordering and notation, but you should benefit by reading any text.

Please let me know if any of the links below are broken.

Overviews of Introductory Quantum Mechanics:

Dirac notation (bra-ket notation) and properties of bra's and ket's:

Please get comfortable with this mathematical formulation. Chapter 2 of Nash notes introduces most of the notation. Here are some more references:

Spin-1/2 systems:

This topic is not covered in Nash's notes. We will use the spin-1/2 system for many examples; so it is important that you get familiar through other sources. Some links below.

Postulates of Quantum Mechanics:

Not covered in Nash's notes. The numbering of postulates varies (is not standardized), but each treatment covers very similar statements.

The Dirac delta function:

Sources for other topics:

Textbooks:

There are many textbooks available on introductory quantum mechanics. I list some sources below.
(I omit publisher and year of publication: the author and title should be enough to identify each textbook.)


Notes on Exam

The exams are TWO HOURS long.

The exam will NOT have a choice of M questions out of N, as was common a few years ago.
You will be asked to answer ALL questions.

Assignment marks (`continuous assessment') will be counted toward the final module mark only if they are to the students' advantage.
(The policy is module-dependent and varies within the Theoretical Physics department. In some modules, continuous assessment is `compulsory'.)
