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…
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…
Critical behavior at the integer quantum Hall transition in a network model on the Kagome lattice
I. A. Gruzberg, N. Charles, A. Klümper +2
We study a network model on the Kagome lattice (NMKL). This model generalizes the Chalker-Coddington (CC) network model for the integer quantum Hall transition. Unlike random netwo…
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…
Localization length index in a Chalker-Coddington model: a numerical study
W. Nuding, A. Klümper, A. Sedrakyan
We calculated numerically the localization length index for the Chalker-Coddington model of the plateau-plateau transitions in the quantum Hall effect. By taking into account f…
The complete conformal spectrum of a invariant network model and logarithmic corrections
Britta Aufgebauer, Michael Brockmann, Win Nuding +2
We investigate the low temperature asymptotics and the finite size spectrum of a class of Temperley-Lieb models. As reference system we use the spin-1/2 Heisenberg chain with aniso…
