Two-dimensional anisotropic non-Hermitian Lieb lattice

L. C. Xie, H. C. Wu, X. Z. Zhang +2

We study an anisotropic two-dimensional non-Hermitian Lieb lattice, where the staggered gain and loss present in the horizontal and vertical directions, respectively. The intra-cel…

Untying links through anti-parity-time-symmetric coupling

H. C. Wu, X. M. Yang, L. Jin +1

We reveal how the vector field links are untied under the influence of anti-parity-time-symmetric couplings in a dissipative sublattice-symmetric topological photonic crystal latti…

Dynamic magnetization in non-Hermitian quantum spin system

X. Z. Zhang, L. Jin, Z. Song

We report a global effect induced by the local complex field, associated with the spin-exchange interaction. High-order exceptional point up to ()-level coalescence is created…

High-order exceptional points in supersymmetric arrays

S. M. Zhang, X. Z. Zhang, L. Jin +1

We employ the intertwining operator technique to synthesize a supersymmetric (SUSY) array of arbitrary size . The synthesized SUSY system is equivalent to a spin- under…

Hybrid exceptional point created from type III Dirac point

L. Jin, H. C. Wu, Bo-Bo Wei +1

Degeneracy (exceptional) points embedded in energy band are distinct by their topological features. We report different hybrid two-state coalescences (EP2s) formed through merging…

Helical resonant transport and purified amplification at an exceptional point

K. L. Zhang, L. Jin, Z. Song

We propose an application of a parity-time symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model by embedded it in a two-dimensional square lattice tube. The coalescence state a…
