Controllable Thouless Pumping Switching Dynamics of Gap Solitons Mediated by Finite Bogoliubov Excitations
Tao Jiang, Jie Liu, Li-Chen Zhao
We investigate the Thouless pumping dynamics of nonlinear gap solitons and attempt to realize topological Chern number switching by modulating nonlinear parameters and varying the…

A corresponding relationship between nonlinear Hermitian systems and linear non-Hermitian models
Yu-Hao Wang, Yan-Hong Qin, Jie Liu +1
We note that the non-orthogonality of states and their coincidence at the degeneracy point are both admitted by nonlinear Hermitian systems and linear non-Hermitian systems. These…
