While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

Entropy also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.
