Superheavy dark-bright soliton as a signature of spatial symmetry breaking transition in harmonically trapped Bose mixtures
Zheng Gao, Ling-Zheng Meng, Jie Liu +1
We investigate the dynamics of a dark-bright soliton in harmonically trapped two-component Bose-Einstein condensates and reveal an interesting spontaneous spatial symmetry breaking…
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…
Controllable excitation of vector Akhmediev breather patterns
Yan-Hong Qin, Ning Cao, Li-Chen Zhao
In the focusing Manakov system, multiple modulation instability (MI) branches coexist on the same plane wave background, so the usual weak periodic modulation cannot selectively ex…
Dirac monopole potentials with high charges underlying nonlinear waves
Yan-Hong Qin, Jin-Peng Yang, Li-Chen Zhao
We investigate topological vector potentials underlying the phases of nonlinear waves by performing Dirac's magnetic monopole theory in an extended complex plane, taking into accou…
Dissipation-induced Nonlinear Topological Gear Switching
Xuzhen Cao, Xiaolin Li, Liang Bai +3
Nonlinear interaction enables topological phenomena impossible in linear systems. A paradigm is nonlinear Thouless pump, where the transport of solitons can be topologically quanti…
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…
