An attractor dynamics in a non-Hermitian two-level system
C. Li, P. Wang, L. Jin +1
Exceptional point in non-Hermitian system possesses fascinating properties. We present an exactly solvable attractor dynamics for the first time from a two-level time dependent non…
Coalescing Majorana edge modes in non-Hermitian PT-symmetric Kitaev chain
Ci. Li, Liang. Jin, Zhi. Song
A single unit cell contains all the information about the bulk system, including the topological feature. The topological invariant can be extracted from a finite system, which con…
Maximal distant entanglement in Kitaev tube
P. Wang, S. Lin, G. Zhang +1
We study the Kitaev model on a finite-size square lattice with periodic boundary conditions in one direction and open boundary conditions in the other. Based on the fact that the M…
Topological phases in Kitaev chain with imbalanced pairing
C. Li, X. Z. Zhang, G. Zhang +1
We systematically study a Kitaev chain with imbalanced pair creation and annihilation, which is introduced by non-Hermitian pairing terms. Exact phase diagram shows that the topolo…
Parallel dynamics between non-Hermitian and Hermitian systems
P. Wang, S. Lin, L. Jin +1
We study the connection between a family of non-Hermitian Hamiltonians H and Hermitian ones H based on exact solutions. In general, for a dynamic process in a non-Hermitian system…
