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 . I…

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…

Random network models with variable disorder of geometry
Andreas Klümper, Win Nuding, Ara Sedrakyan
Recently it was shown (I.A.Gruzberg, A. Klümper, W. Nuding and A. Sedrakyan, Phys.Rev.B 95, 125414 (2017)) that taking into account random positions of scattering nodes in the netw…
