Quartic multifractality and finite-size corrections at the spin quantum Hall transition
Quartic multifractality and finite-size corrections at the spin quantum Hall transition
The spin quantum Hall transition (or class C transition in two dimensions) represents one of the few localization-delocalization transitions for which some of the critical exponents are known exactly. Not known, however, is the multifractal spectrum ${\ensuremath{\tau}}_{q}$, which describes the system-size scaling of inverse participation ratios ${P}_{q}$, i.e., the $q$ …
