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…
Long-range entangled zero-mode state in a non-Hermitian lattice
S. Lin, X. Z. Zhang, C. Li +1
In contrast to a Hermitian system, in which zero modes are usually degenerate and localized edge state in the thermodynamic limit, the zero mode of a finite non-Hermitian system ca…
Magnetic-flux-driven topological quantum phase transition and manipulation of perfect edge states in graphene tube
S. Lin, G. Zhang, C. Li +1
We study the tight-binding model for a graphene tube with perimeter N threaded by a magnetic field. We show exactly that this model has different nontrivial topological phases as t…
