Stable dynamic helix state in the nonintegrable XXZ Heisenberg model

Gang Zhang, Zhi Song

We investigate the influence of external fields on the stability of spin helix states in an XXZ Heisenberg model. Exact diagonalization on a finite system shows that random transve…

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…

Impact of single string structure and multiple string interaction on strangeness production in Pb+Pb collisions at TeV

Dai-Mei Zhou, Liang Zheng, Zhi-Hong Song +5

We present a systematic study on the strange and multi-strange particles production in Pb+Pb collisions at TeV based on the PACIAE model simulations. Two dif…

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…

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…
