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…
Su-Schrieffer-Heeger chain with one pair of PT-symmetric defects
L. Jin, P. Wang, Z. Song
The topologically nontrivial edge states induce PT transition in Su-Schrieffer-Heeger (SSH) chain with one pair of gain and loss at boundaries. In this study, we investigated a pai…
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…
Non-Hermitian description of the dynamics of inter-chain pair tunnelling
X. Z. Zhang, L. Jin, Z. Song
We study inter-chain pair tunnelling dynamics based on an exact two-particle solution for a two-leg ladder. We show that the Hermitian Hamiltonian shares a common two-particle eige…
