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…
