Interplay of , point group and translation symmetry for PEPS: application to a chiral spin liquid
Anna Hackenbroich, Antoine Sterdyniak, Norbert Schuch
Projected entangled pair states (PEPS) provide exact representations for many non-chiral topologically ordered states whereas their range of applicability to interacting chiral top…
Creating a bosonic fractional quantum Hall state by pairing fermions
Cécile Repellin, Tarik Yefsah, Antoine Sterdyniak
We numerically study the behavior of spin-- fermions on a two-dimensional square lattice subject to a uniform magnetic field, where opposite spins interact via an on-site attr…
Nature of chiral spin liquids on the kagome lattice
Alexander Wietek, Antoine Sterdyniak, Andreas M. Läuchli
We investigate the stability and the nature of the chiral spin liquids which were recently uncovered in extended Heisenberg models on the kagome lattice. Using a Gutzwiller project…
Series of Abelian and Non-Abelian States in C>1 Fractional Chern Insulators
A. Sterdyniak, C. Repellin, B. Andrei Bernevig +1
We report the observation of a new series of Abelian and non-Abelian topological states in fractional Chern insulators (FCI). The states appear at bosonic filling nu= k/(C+1) (k, C…
Quasiparticles and excitons for the Pfaffian quantum Hall state
I. D. Rodriguez, A. Sterdyniak, M. Hermanns +2
We propose trial wave functions for quasiparticle and exciton excitations of the Moore-Read Pfaffian fractional quantum Hall states, both for bosons and for fermions, and study the…
Hierarchical structure in the orbital entanglement spectrum in Fractional Quantum Hall systems
A. Sterdyniak, B. A. Bernevig, N. Regnault +1
We investigate the non-universal part of the orbital entanglement spectrum (OES) of the nu = 1/3 fractional quantum Hall effect (FQH) ground-state with Coulomb interactions. The no…
Extracting Excitations From Model State Entanglement
A. Sterdyniak, N. Regnault, B. A. Bernevig
We extend the concept of entanglement spectrum from the geometrical to the particle bipartite partition. We apply this to several Fractional Quantum Hall (FQH) wavefunctions on bot…
