Non-Hermitian topological end breathers
Li-Jun Lang, Shi-Liang Zhu, Y. D. Chong
Nonlinearities in lattices with topologically nontrivial band structures can give rise to topological solitons, whose properties differ from both conventional lattice solitons and…
Dynamical robustness of topological end states in nonreciprocal Su-Schrieffer-Heeger models with open boundary conditions
Li-Jun Lang, Yijiao Weng, Yunhui Zhang +2
For non-Hermitian quantum models, the dynamics is apparently not reflected by the static properties, e.g., the complex energy spectrum, because of the nonorthogonality of the right…
Non-Hermitian Topological Anderson Insulators
Dan-Wei Zhang, Ling-Zhi Tang, Li-Jun Lang +2
Non-Hermitian systems can exhibit unique topological and localization properties. Here we elucidate the non-Hermitian effects on disordered topological systems by studying a non-He…
Non-Hermitian dynamics of slowly-varying Hamiltonians
Hailong Wang, Li-Jun Lang, Y. D. Chong
We develop a theoretical description of non-Hermitian time evolution that accounts for the break- down of the adiabatic theorem. We obtain closed-form expressions for the time-depe…
