Symmetry protected topological phases characterized by isolated exceptional points
S. Lin, L. Jin, Z. Song
Exceptional point (EP) associated with eigenstates coalescence in non-Hermitian systems has many exotic features. The EPs are generally sensitive to system parameters, here we repo…
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 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…
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…
Wide-range-tunable Dirac-cone band structure in a chiral-time-symmetric non-Hermitian system
S. Lin, Z. Song
We establish a connection between an arbitrary Hermitian tight-binding model with chiral (C) symmetry and its non-Hermitian counterpart with chiral-time (CT ) symmetry.We show that…
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…
