Antihelical Edge States in Two-dimensional Photonic Topological Metals
L. C. Xie, L. Jin, Z. Song
Topological edge states are the core of topological photonics. Here we introduce the antihelical edge states of time-reversal symmetric topological metals and propose a photonic re…
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…
Resonant-amplified and invisible Bragg scattering based on spin coalescing modes
K. L. Zhang, Z. Song
Unlike a real magnetic field, which separates the energy levels of particle with opposite spin polarization, a complex field can lead to a special kind of spectral degeneracy, know…
Dynamic crystallization in a quantum Ising chain
K. L. Zhang, Z. Song
The topological degeneracy of ground states in transverse field Ising chain cannot be removed by local perturbation and allows it to be a promising candidate for topological comput…
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…
