Higher-order topological insulators are unusual materials that can support topologically protected states.
Controllable deformations presented in periodic structures might result in the appearance of disclinations and set the new stages for the construction of higher-order topological insulators with varied distinct rotational symmetries, which were noticed until now only in linear regime.
