Projectively topological exceptional points in non-Hermitian Rice-Mele model
C. Li, Z. Song
We study coupled non-Hermitian Rice-Mele chains, which consist of Su-Schrieffer-Heeger (SSH) chain system with staggered on-site imaginary potentials. In two dimensional (2D) therm…
Dynamical signature of moire pattern in non-Hermitian ladder
X. M. Yang, X. Z. Zhang, C. Li +1
We study the dynamical behavior of a non-Hermitian moire superlattice system, which consists of two-coupled SSH chains with staggered imaginary on-site potentials. There are two ma…
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…
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…
Topological nodal points in two coupled SSH chains
Ci. Li, Sen. Lin, Gang. Zhang +1
We study two coupled Su-Schrieffer-Heeger (SSH) chains system, which is shown to contain rich quantum phases associated with topological invariants protected by symmetries. In the…
Quantum phase transition induced by real-space topology
C. Li, G. Zhang, S. Lin +1
A quantum phase transition (QPT), including both topological and symmetry breaking types, is usually induced by the change of global parameters, such as external fields or global c…
