Dynamics of Dissipative Quantum Hall Edges [PDF]

, 2003
We examine the influence of the edge electronic density profile and of dissipation on edge magnetoplasmons in the quantum Hall regime, in a semiclassical calculation.

Casimir Edge Effects

Physical Review Letters, 2006
We compute Casimir forces in open geometries with edges, involving parallel as well as perpendicular semi-infinite plates. We focus on Casimir configurations which are governed by a unique dimensional scaling law with a universal coefficient. With the aid of worldline numerics, we determine this coefficient for various geometries for the case of scalar-

Zero-field dissipationless chiral edge transport and the nature of dissipation in the quantum anomalous Hall state [PDF]

, 2015
The quantum anomalous Hall (QAH) effect is predicted to possess, at zero magnetic field, chiral edge channels that conduct spin polarized current without dissipation.

Impact of edge shape on the functionalities of graphene-based single-molecule electronics devices [PDF]

, 2012
We present an ab-initio analysis of the impact of edge shape and graphene-molecule anchor coupling on the electronic and transport functionalities of graphene-based molecular electronics devices.

Luttinger States at the Edge [PDF]

, 1994
An effective wavefunction for the edge excitations in the Fractional quantum Hall effect can be found by dimensionally reducing the bulk wavefunction. Treated this way the Laughlin $\nu=1/(2n+1)$ wavefunction yields a Luttinger model ground state.

Experimental investigation of the edge states structure at fractional filling factors

, 2005
We experimentally study electron transport between edge states in the fractional quantum Hall effect regime. We find an anomalous increase of the transport across the 2/3 incompressible fractional stripe in comparison with theoretical predictions for the

The Role of Interactions in an Electronic Fabry-Perot Interferometer Operating in the Quantum Hall Effect Regime [PDF]

, 2009
Interference of edge channels is expected to be a prominent tool for studying statistics of charged quasiparticles in the quantum Hall effect (QHE) [A. Stern (2008), Ann. Phys. 1:204; C. Chamon et al. (1997), Phys. Rev. B, 55:2331].

Edge Effects and Huanglongbing [PDF]

Journal of Citrus Pathology, 2014
Huanglongbing (HLB), spread by a psyllid vector, is globally considered a major threat to commercial and sustainable citrus production. Better understanding of the vector-mediated patterns of HLB spread is essential to inform and maximize disease management. From previous studies, edge effects are a significant characteristic of the HLB pathosystem and

Effective spin dephasing mechanism in confined two-dimensional topological insulators

, 2016
A Kramers pair of helical edge states in quantum spin Hall effect (QSHE) is robust against normal dephasing but not robust to spin dephasing. In our work, we provide an effective spin dephasing mechanism in the puddles of two-dimensional (2D) QSHE, which

Domination game: Effect of edge contraction and edge subdivision

Discussiones Mathematicae Graph Theory, 2020
Summary: In this paper the behavior of the game domination number \(\gamma_g(G)\) and the Staller start game domination number \(\gamma_g^\prime(G)\) by the contraction of an edge and the subdivision of an edge are investigated. Here we prove that contracting an edge can decrease \(\gamma_g(G)\) and \(\gamma_g^\prime(G)\) by at most two, whereas ...
