Topological liquid nucleation induced by vortex-vortex interactions in Kitaev's honeycomb model
Ville Lahtinen, Andreas W. W. Ludwig, Jiannis K. Pachos +1
We provide a comprehensive microscopic understanding of the nucleation of topological quantum liquids, a general mechanism where interactions between non-Abelian anyons cause a tra…
Strong potential impurities on the surface of a topological insulator
Annica M. Black-Schaffer, Alexander V. Balatsky
Topological insulators (TIs) are said to be stable against non-magnetic impurity scattering due to suppressed backscattering in the Dirac surface states. We solve a lattice model o…
Charge Fractionalization on Quantum Hall Edges
Mats Horsdal, Marianne Rypestøl, Hans Hansson +1
We discuss the propagation and fractionalization of localized charges on the edges of quantum Hall bars of variable widths, where interactions between the edges give rise to Luttin…
Interacting non-Abelian anyons as Majorana fermions in the honeycomb lattice model
Ville Lahtinen
We study the collective states of interacting non-Abelian anyons that emerge in Kitaev's honeycomb lattice model. Vortex-vortex interactions are shown to lead to the lifting of the…
