Bulk-hole correspondence and inner robust boundary modes in singular flatband lattices
Limin Song, Shenyi Gao, Shiqi Xia +5
Topological entities based on bulk-boundary correspondence are ubiquitous, from conventional to higher-order topological insulators, where the protected states are typically locali…

Topologically protected vortex transport via chiral-symmetric disclination
Zhichan Hu, Domenico Bongiovanni, Ziteng Wang +6
Vortex phenomena are ubiquitous in nature, from vortices of quantum particles and living cells [1-7], to whirlpools, tornados, and spiral galaxies. Yet, effective control of vortex…

Robustness versus sensitivity in non-Hermitian topological lattices probed by pseudospectra
I. Komis, D. Kaltsas, S. Xia +3
Non-Hermitian topological systems simultaneously posses two antagonistic features: ultra sensitivity due to exceptional points and robustness of topological zero energy modes, and…
