Condensate-induced transitions and critical spin chains
Teresia Mansson, Ville Lahtinen, Juha Suorsa +1
We show that condensate-induced transitions between two-dimensional topological phases provide a general framework to relate one-dimensional spin models at their critical points. W…
A general approach to quantum Hall hierarchies
J. Suorsa, S. Viefers, T. H. Hansson
The abelian hierarchy of quantum Hall states accounts for most of the states in the lowest Landau level, and there is evidence of a similar hierarchy of non-abelian states emanatin…
Effective spin chains for fractional quantum Hall states
Emil J. Bergholtz, Masaaki Nakamura, Juha Suorsa
Fractional quantum Hall (FQH) states are topologically ordered which indicates that their essential properties are insensitive to smooth deformations of the manifold on which they…
Disentangling Entanglement Spectra of Fractional Quantum Hall States on Torus Geometries
Andreas M. Laeuchli, Emil J. Bergholtz, Juha Suorsa +1
We analyze the entanglement spectrum of Laughlin states on the torus and show that it is arranged in towers, each of which is generated by modes of two spatially separated chiral e…
Link between the hierarchy of fractional quantum Hall states and Haldane's conjecture for quantum spin chains
Masaaki Nakamura, Emil J. Bergholtz, Juha Suorsa
We study a strong coupling expansion of the fractional quantum Hall state away from the Tao-Thouless limit and show that the leading quantum fluctuations lead to an effecti…
Fractional periodicity and magnetism of extended quantum rings
Y. Hancock, J. Suorsa, E. Tölö +1
The magnetic properties and nature of the persistent current in small flux-penetrated rings are investigated. An effective rigid-rotator description is formulated for this…
