Klaus von Klitzing is the discoverer of QHE (Nobel Prize 1985). These notes are self-contained, but still supplementing the text; DO NOT ignore the text, even if it is confusing like hell 😛
Syed Azeez Sir’s Quantum Notes. A few pages may be blurry, but they are still fairly legible.
This is some extra stuff for the interested folk.
