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…
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…
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…
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…
