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…
Quantum Hall Physics with Cold Atoms in Cylindrical Optical Lattices
Mateusz Łącki, Hannes Pichler, Antoine Sterdyniak +5
We propose and study various realizations of a Hofstadter-Hubbard model on a cylinder geometry with fermionic cold atoms in optical lattices. The cylindrical optical lattice is cre…
Bosonic integer quantum Hall effect in optical flux lattices
A. Sterdyniak, Nigel R. Cooper, N. Regnault
In two dimensions strongly interacting bosons in a magnetic field can realize a bosonic integer quantum Hall state, the simplest two dimensional example of a symmetry protected top…
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…
Interacting bosons in topological optical flux lattices
A. Sterdyniak, B. Andrei Bernevig, Nigel R. Cooper +1
An interesting route to the realization of topological Chern bands in ultracold atomic gases is through the use of optical flux lattices. These models differ from the tight-binding…
Particle Entanglement Spectra for Quantum Hall states on Lattices
A. Sterdyniak, N. Regnault, G. Moller
We use particle entanglement spectra to characterize bosonic quantum Hall states on lattices, motivated by recent studies of bosonic atoms on optical lattices. Unlike for the relat…
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…
Real-Space Entanglement Spectrum of Quantum Hall States
A. Sterdyniak, A. Chandran, N. Regnault +2
We investigate the entanglement spectra arising from sharp real-space partitions of the system for quantum Hall states. These partitions differ from the previously utilized orbital…
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…
