Quantum Hall quasielectron operators in conformal field theory
T. H. Hansson, M. Hermanns, S. Viefers
In the conformal field theory (CFT) approach to the quantum Hall effect, the multi-electron wave functions are expressed as correlation functions in certain rational CFTs. While th…
Current-spin-density functional study of persistent currents in quantum rings
S. Viefers, P. Singha Deo, S. M. Reimann +2
We present a numerical study of persistent currents in quantum rings using current spin density functional theory (CSDFT). This formalism allows for a systematic study of the joint…
Broken Symmetries in the Reconstruction of v=1 Quantum Hall Edges
S. M. Reimann, M. Koskinen, S. Viefers +2
Spin-polarized reconstruction of the v=1 quantum Hall edge is accompanied by a spatial modulation of the charge density along the edge. We find that this is also the case for finit…
Edge Theories for Polarized Quantum Hall States
T. H. Hansson, S. Viefers
Starting from recently proposed bosonic mean field theories for fully and partially polarized quantum Hall states, we construct corresponding effective low energy theories for the…
The effect of interactions on Bose-Einstein condensation in a two-dimensional harmonic trap
R. K. Bhaduri, S. M. Reimann, S. Viefers +2
A dilute bose gas in a quasi two-dimensional harmonic trap and interacting with a repulsive two-body zero-range potential of fixed coupling constant is considered. Using the Thomas…
