Spin Quantum Hall Effect: the Critical Exponents
Hrant Topchyan, Win Nuding, Andreas Klümper +1
The spin quantum Hall effect (SQHE) provides one of the few examples of an Anderson localization transition for which exact critical exponents are known, making it an important tes…

The integer quantum Hall transition: an -matrix approach to random networks
Hrant Topchyan, Ilya Gruzberg, Win Nuding +2
In this paper we propose a new -matrix approach to numerical simulations of network models and apply it to random networks that we proposed in a previous work 10.1103/PhysRevB.9…

Harris-Luck criterion in the plateau transition of the Integer Quantum Hall Effect
Hrant Topchyan, Win Nuding, Andreas Klümper +1
The Harris criterion imposes a constraint on the critical behavior of a system upon introduction of new disorder, based on its dimension and localization length exponent .…
