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…
Statistical properties of quadrangular surfaces
Hrant Topchyan, Rudik Badalyan, Ara Sedrakyan
We investigate the statistical properties of random quadrangular surfaces generated by different randomization procedures: the Gruzberg-Klümper-Nuding-Sedrakyan (GKNS) construction…
Nucleation of Sachdev-Ye-Kitaev Clusters in One Spatial Dimension
Hrant Topchyan, Tigran A. Sedrakyan
We study how Sachdev-Ye-Kitaev (SYK) interactions can arise from localized single-particle states on a system that is effectively one dimensional. If a local interaction is project…
The symmetry protected boundary modes in two-dimensional Potts paramagnets
Hrant Topchyan
We construct and analyze a class of one-dimensional boundary Hamiltonians arising from two-dimensional symmetry-protected topological phases with symmetry…
