Quantum rings for beginners II: Bosons versus fermions
M. Manninen, S. Viefers, S. M. Reimann
The purpose of this overview article, which can be viewed as a supplement to our previous review on quantum rings, [S. Viefers {\it et al}, Physica E {\bf 21} (2004), 1-35], is to…
Quantum Hall quasielectrons - Abelian and non-Abelian
T. H. Hansson, M. Hermanns, N. Regnault +1
The quasiparticles in Quantum Hall liquids carry fractional charge and obey fractional quantum statistics. Of particular recent interest are those with non-Abelian statistics, sinc…
Quantum Hall physics in rotating Bose-Einstein condensates
Susanne Viefers
The close theoretical analogy between the physics of rapidly rotating atomic Bose condensates and the quantum Hall effect (i.e., a two dimensional electron gas in a strong magnetic…
Hierarchy wave functions--from conformal correlators to Tao-Thouless states
E. J. Bergholtz, T. H. Hansson, M. Hermanns +2
Laughlin's wave functions, describing the fractional quantum Hall effect at filling factors , can be obtained as correlation functions in conformal field theory, and re…
Composite fermion wave functions as conformal field theory correlators
Hans Hansson, Chia-Chen Chang, Jainendra Jain +1
It is known that a subset of fractional quantum Hall wave functions has been expressed as conformal field theory (CFT) correlators, notably the Laughlin wave function at filling fa…
Conformal Field Theory of Composite Fermions
T. H. Hansson, C. -C. Chang, J. K. Jain +1
We show that the quantum Hall wave functions for the ground states in the Jain series can be exactly expressed in terms of correlation functions of local vertex operators, V_n, cor…
Composite-fermion description of rotating Bose gases at low angular momenta
Nicolay Korslund, Susanne Viefers
We study the composite fermion construction at and below the single vortex () state of weakly interacting rotating Bose gases, presenting a new method for handling the large n…
Effects of surface forces and phonon dissipation in a three-terminal nano relay
L. M. Jonsson, T. Nord, S. Viefers +1
We have performed a theoretical analysis of the operational characteristics of a carbon-nanotube-based three-terminal nanorelay. We show that short range and van der Waals forces h…
Energy spectrum, persistent current and electron localization in quantum rings
M. Manninen, P. Koskinen, M. Koskinen +3
Energy spectra of quasi-one-dimensional quantum rings with a few electrons are studied using several different theoretical methods. Discrete Hubbard models and continuum models are…
Quantum rings for beginners: Energy spectra and persistent currents
S. Viefers, P. Koskinen, P. Singha Deo +1
Theoretical approaches to one-dimensional and quasi-one-dimensional quantum rings with a few electrons are reviewed. Discrete Hubbard-type models and continuum models are shown to…
Many-body spectrum and particle localization in quantum dots and finite rotating Bose condensates
M. Manninen, S. Viefers, M. Koskinen +1
The yrast spectra (i.e. the lowest states for a given total angular momentum) of quantum dots in strong magnetic fields, are studied in terms of exact numerical diagonalization and…
Bulk and edge properties of the Chern-Simons Ginzburg-Landau theory for the fractional quantum Hall effect
Jon Magne Leinaas, Susanne Viefers
The Chern-Simons Ginzburg-Landau theory for the fractional Quantum Hall effect is studied in the presence of a confining potential. We review the bulk properties of the model and d…
