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…
