Symmetry and topological classification of Floquet non-Hermitian systems
Chun-Hui Liu, Haiping Hu, Shu Chen
Recent experimental advances in Floquet engineering and controlling dissipation in open systems have brought about unprecedented flexibility in tailoring novel phenomena without an…
Knot topology of exceptional point and non-Hermitian no-go theorem
Haiping Hu, Shikang Sun, Shu Chen
Exceptional points (EPs) are peculiar band singularities and play a vital role in a rich array of unusual optical phenomena and non-Hermitian band theory. In this paper, we provide…
Illuminating the bulk-boundary correspondence of a non-Hermitian stub lattice with Majorana stars
James Bartlett, Haiping Hu, Erhai Zhao
Topological characterization of non-Hermitian band structures demands more than a straightforward generalization of the Hermitian cases. Even for one-dimensional tight-binding mode…
Dynamical signatures of point-gap Weyl semimetal
Haiping Hu, Erhai Zhao, W. Vincent Liu
We demonstrate a few unique dynamical properties of point-gap Weyl semimetal, an intrinsic non-Hermitian topological phase in three dimensions. We consider a concrete model where a…
