Universal signatures of Dirac fermions in entanglement and charge fluctuations
Valentin Crépel, Anna Hackenbroich, Nicolas Regnault +1
We investigate the entanglement entropy (EE) and charge fluctuations in models where the low energy physics is governed by massless Dirac fermions. We focus on the response to flux…
Fractional Chiral Hinge Insulator
Anna Hackenbroich, Ana Hudomal, Norbert Schuch +2
We propose and study a wave function describing an interacting three-dimensional fractional chiral hinge insulator (FCHI) constructed by Gutzwiller projection of two non-interactin…
Fermionic tensor networks for higher order topological insulators from charge pumping
Anna Hackenbroich, B. Andrei Bernevig, Norbert Schuch +1
We apply the charge pumping argument to fermionic tensor network representations of d-dimensional topological insulators (TIs) to obtain tensor network states for (d+1)-dimensional…
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…
Parent Hamiltonians for lattice Halperin states from free-boson conformal field theories
Anna Hackenbroich, Hong-Hao Tu
We introduce a family of many-body quantum states that describe interacting spin one-half hard-core particles with bosonic or fermionic statistics on arbitrary one- and two-dimensi…
