Lattice defects in topological phases of matter — •Alexander Gavrishev1,2, Alexander Wong2, Henry Davenport2, Andres Perez Fadon2, and Frank Schindler2 — 1Max Planck Institute for the Physics of Complex Systems — 2Imperial College London
The defect response of topological materials offers a potential starting point for experimental probes of topology; while many comprehensive results exist for simple lattice defects in non-interacting topological matter, an analogue for interacting topological phases is missing. As a first step in this direction, we present exact diagonalisation results for lattice dislocations in a fractional Chern insulator.
Keywords: fractional Chern insulator; lattice defect; topological order; exact diagonalisation
