Experimentally Detecting Quantized Zak Phases without Chiral Symmetry in Photonic Lattices
Experimentally Detecting Quantized Zak Phases without Chiral Symmetry in Photonic Lattices
Symmetries play a major role in identifying topological phases of matter and in establishing a direct connection between protected edge states and topological bulk invariants via the bulk-boundary correspondence. One-dimensional lattices are deemed to be protected by chiral symmetry, exhibiting quantized Zak phases and protected edge states, but not for …
