Directed motion of domain walls in biaxial ferromagnets under the influence of periodic external magnetic fields
Yaroslav Zolotaryuk, Maxim M. Osmanov
Directed motion of domain walls (DWs) in a classical biaxial ferromagnet placed under the influence of periodic unbiased external magnetic fields is investigated. Using the symmetr…
Resonant fluxon transmission through impurities
Yaroslav Zolotaryuk
Fluxon transmission through several impurities of different strength and type (i.e., microshorts and microresistors), placed in a long Josephson junction is investigated. Threshold…
Long-range effects on superdiffusive solitons in anharmonic chains
C. Brunhuber, F. G. Mertens, Y. Gaididei
Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Ka…
Discrete soliton ratchets driven by biharmonic fields
Yaroslav Zolotaryuk, Mario Salerno
Directed motion of topological solitons (kinks or antikinks) in the damped and AC-driven discrete sine-Gordon system is investigated. We show that if the driving field breaks certa…
Bubble generation in a twisted and bent DNA-like model
Peter V. Larsen, Peter L. Christiansen, Ole Bang +2
The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investig…
Energy funneling in a bent chain of Morse oscillators with long-range coupling
P. V. Larsen, P. L. Christiansen, O. Bang +2
A bent chain of coupled Morse oscillators with long-range dispersive interaction is considered. Moving localized excitations may be trapped in the bending region. Thus chain geomet…
