Spin chain description of rotating bosons at

Emma Wikberg, Emil J. Bergholtz, Anders Karlhede

We consider bosons at Landau level filling on a thin torus. In analogy with previous work on fermions at filling , we map the low-energy sector onto a spin-1/2 chain.…

Quantum Hall Circle

E. J. Bergholtz, A. Karlhede

We consider spin-polarized electrons in a single Landau level on a cylinder as the circumference of the cylinder goes to infinity. This gives a model of interacting electrons on a…

Dissipation in circuit quantum electrodynamics: lasing and cooling of a low-frequency oscillator

Julian Hauss, Arkady Fedorov, Stephan André +6

Superconducting qubits coupled to electric or nanomechanical resonators display effects previously studied in quantum electrodynamics (QED) and extensions thereof. Here we study a…

Degeneracy of non-abelian quantum Hall states on the torus: domain walls and conformal field theory

Eddy Ardonne, Emil J. Bergholtz, Janik Kailasvuori +1

We analyze the non-abelian Read-Rezayi quantum Hall states on the torus, where it is natural to employ a mapping of the many-body problem onto a one-dimensional lattice model. On t…

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…

Quantum Hall system in Tao-Thouless limit

E. J. Bergholtz, A. Karlhede

We consider spin-polarized electrons in a single Landau level on a torus. The quantum Hall problem is mapped onto a one-dimensional lattice model with lattice constant , wh…
