Emerging topological characterization in non-equilibrium states of quenched Kitaev chains
Y. B. Shi, X. Z. Zhang, Z. Song
Topological characteristics of quantum systems are typically determined by the closing of a gap, while the dynamical quantum phase transition (DQPT) during quantum real-time evolut…
Generalized phantom helix states in quantum spin graphs
C. H. Zhang, Y. B. Shi, Z. Song
In general, the summation of a set of sub-Hamiltonians cannot share a common eigenstate of each one, only if it is an unentangled product state, such as a phantom helix state in qu…
Robust unidirectional phantom helix states in the XXZ Heisenberg model with Dzyaloshinskii-Moriya interaction
Y. B. Shi, Z. Song
The phantom helix states are a special set of degenerate eigenstates of the XXZ Heisenberg model, which lie in the energy levels around zero energy and are bidirectionally equal. I…
Fixed lines in a non-Hermitian Kitaev chain with spatially balanced pairing processes
Y. B. Shi, Z. Song
Exact solutions for non-Hermitian quantum many-body systems are rare but may provide valuable insights into the interplay between Hermitian and non-Hermitian components. We report…
