Signature of edge states in resonant wave scattering
H. S. Xu, K. L. Zhang, L. Jin +1
Particle beam scattering is a conventional technique for detecting the nature of matter. We studied the scattering problem of a cluster connected to multiple leads. We established…
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…
Ising chain with topological degeneracy induced by dissipation
K. L. Zhang, Z. Song
The ground-state degeneracy of the quantum spin system is a characteristic of nontrivial topology, when it is gapped and robust against disordered perturbation. The corresponding q…
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…
Manifestation of a topological gapless phase in a two-dimensional chiral symmetric system through Loschmidt echo
K. L. Zhang, Z. Song
Unlike the edge state of a topological insulator where its energy level lives in the bulk energy gap, the edge state of a topological semimetal hides in the bulk spectrum and is di…
