Curriculum and exercises
Curriculum
The curriculum is defined by the lectures which in turn will follow closely "Intermediate Quantum Mechanics". A summary of most of the content in the course is found here.
To get access to this book, sign up for a free account on Bookboon.com, search for the title on Bookboon.com, and then press download.
Additional notes relevant for curriculum:
Periodic potentials/band theory in "Introduction to Quantum Mechanics".
Extra material on exchange interaction, variational principle and singlet states
Derivation of minimal coupling p-qA in Lagrangian formalism/classical mechanics
Extra material on Landau levels in graphene and hopping model
Extra material on entanglement (see topic 5). The part relevant for the curriculum is everything from the start up to 5.1.4, from the beginning of 5.3 to 5.3.1, and from the start of 5.3.2 up to "Schmidt decomposition". The teaching goals for the part on entanglement are found here.
See section "A useful choice" on page 5 here for an explanation of why we can set <n|n^1>=0 in time-indepenent perturbation theory.
Note on rotation operator for spin-1/2 particles.
You can also find some of the above material covered in the Norwegian textbook "Kvantemekanikk" by P. C. Hemmer.
