## Title

  title_type: original

## Description

- description: We investigate higher-order topological states in honeycomb lattice
    with Y-Kekulé distortions that preserve C6v crystalline symmetry. The gapped states
    in expanded and shrunken distortions are adiabatically connected to isolated hexamers
    and Y-shaped tetramer states, respectively, where the former possesses nontrivial
    higher-order topology characterized by a Z6 invariant. Topological corner states
    exist in a flake structure with expanded distortion where the hexamers are broken
    at the corners. Our work reveals that honeycomb lattice with Y-Kekulé distortions
    serves as a promising platform to study higher-order topological states.
