Entanglement manifestation of knot topology in a non-Hermitian lattice
Guoying Zhang, Li Wang, Shu Chen
Although the homotopy-knot theory has been utilized to implement effective topological classification for non-Hermitian systems, the physical implications underlying distinct knot…

Classical correspondence of the exceptional points in the finite non-Hermitian system
X. Z. Zhang, G. Zhang, Z. Song
We systematically study the topology of the exceptional point (EP) in the finite non-Hermitian system. Based on the concrete form of the Berry connection, we demonstrate that the e…

Topological phases in Kitaev chain with imbalanced pairing
C. Li, X. Z. Zhang, G. Zhang +1
We systematically study a Kitaev chain with imbalanced pair creation and annihilation, which is introduced by non-Hermitian pairing terms. Exact phase diagram shows that the topolo…
