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…

Soliton Thouless pumping engineered by inter-site nonlinearities
Tao Jiang, Li-Chen Zhao
We study soliton Thouless pumping in an extended diagonal Aubry-André-Harper model with on-site nonlinearities and inter-site nonlinearities. We show that the inter-site nonlinear…

Dirac monopole magnets in non-Hermitian systems
Haiyang Yu, Tao Jiang, Li-Chen Zhao
We theoretically establish that non-Hermitian perturbations induce a topological transformation of point-like Dirac monopoles into extended monopole distributions, characterized by…
