M. M. Bogdan, O. V. Charkina

摘要:

研究了一维高色散系统中拓扑孤子(位错、畴壁、磁通子)及其束缚态的非定常动力学。研究了运动扭折辐射和呼吸子的动力学特性。给出了呼吸器激励的条件及其动力学性质。孤子复合体的形成过程中的色散,孤子速度,孤子之间的距离的强度进行了分析和数值研究。结果表明,在耗散介质中,具有内部结构的运动束缚孤子复合体可被外力稳定,其速度与驱动强度呈阶跃关系。

英文摘要:

The nonstationary dynamics of topological solitons (dislocations, domain walls, fluxons) and their bound states in one-dimensional systems with high dispersion are investigated. Dynamical features of a moving kink emitting radiation and breathers are studied analytically. Conditions of the breather excitation and its dynamical properties are specified. Processes of soliton complex formation are studied analytically and numerically in relation to the strength of the dispersion, soliton velocity, and distance between solitons. It is shown that moving bound soliton complexes with internal structure can be stabilized by an external force in a dissipative medium then their velocities depend in a step-like manner on a driving strength.
