Novel Transition Mechanisms of Vector Localized Waves Induced by the Fourth-Order Effect
Rong Han, Muchen Dong, Lei Wang
We investigate novel vector localized wave solutions in the coupled Lakshmanan-Porsezian-Daniel equa?tions, which describe the dynamics of the Heisenberg ferromagnetic spin chain.…

Mechanism of State Transitions for the Vector Kuznetsov-Ma Breathers
Muchen Dong, Lei Wang
We study two types of mechanisms of state transitions for vector Kuznetsov-Ma breathers (KMBs) in the coupled Fokas-Lenells framework on unequal backgrounds. The amplitude imbalanc…

Real-Spectrum Darboux Limits at Multiple Spatial Roots of the Coupled Fokas-Lenells System
Muchen Dong, Lei Wang
We investigate Darboux constructions generated by multiple spatial roots of the coupled Fokas-Lenells system on a plane-wave background. Nonreal double roots give regular one-fold…
