One-dimensional soliton dynamics in the presence of a pinning potential

Show other versions (1)

The dissipative effect of (what could be modeled as) a pinning center on the lowamplitude motion of a quasi-one-dimensional ferromagnetic soliton (domain wall) at temperature T = 0 is investigated. The method of collective coordinates is used to eliminate the problem of the zero-frequency eigenmo...
