Journal ArticleDOI
Effective-action studies of quantum hall spin textures
TL;DR: In this paper, an analytic and numerical study of spin textures in quantum Hall systems using a long-wavelength effective action for the magnetic degrees of freedom derived previously is presented. But the majority of the results concern skyrmions or solitons of this action.
Journal ArticleDOI
Fractional spin for quantum Hall effect quasiparticles
TL;DR: In this article, the authors investigate the issue of whether quasiparticles in the fractional quantum Hall effect possess a fractional intrinsic spin, which is suggested by the spin-statistics relation S = θ/2π, with θ being the statistical angle.
Journal ArticleDOI
Clustering in Hilbert space of a quantum optimization problem
TL;DR: It is shown that an analogous quantum clustering phenomenon takes place in the ground state subspace of a certain quantum optimization problem, which involves extending the notion of clustering to Hilbert space, where the classical Hamming distance is not immediately useful.
Journal ArticleDOI
Notes on infinite layer quantum Hall systems
TL;DR: In this article, the fractional quantum Hall effect in three-dimensional systems consisting of infinitely many stacked two-dimensional electron gases placed in transverse magnetic fields was studied, and the surface conduction in these phases was analyzed by means of sum rule and renormalization group arguments.
Journal ArticleDOI
Typology for quantum Hall liquids

TL;DR: There is a close analogy between the response of a quantum Hall liquid (QHL) to a small change in the electron density and the response a superconductor to an externally applied magnetic flux, an analogy made concrete in the Chern-Simons Landau-Ginzburg (CSLG) formulation of the problem as mentioned in this paper.
