Dynamics of the topological structures in inhomogeneous media
L. A. Ferreira, B. Piette, W. J. Zakrzewski
We present a general review of the dynamics of topological solitons in 1 and 2 dimensions and then discuss some recent work on the scattering of various solitonic objects (such as…
Wobbles and other kink-breather solutions of the Sine Gordon model
L. A. Ferreira, Bernard Piette, Wojtek J. Zakrzewski
We study various solutions of the Sine Gordon model in (1+1) dimensions. We use the Hirota method to construct some of them and then show that the wobble, discussed in detail by Kä…
Scattering of Topological Solitons on Barriers and Holes in Two λϕ^4 Models
Jassem H. Al-Alawi, Wojtek J. Zakrzewski
We present results of our studies of various scattering properties of topological solitons on obstructions in the form of holes and barriers in 1+1 dimensions. Our results are base…
Acceleration-Extended Galilean Symmetries with Central Charges and their Dynamical Realizations
J. Lukierski, P. C. Stichel, W. J. Zakrzewski
We add to Galilean symmetries the transformations describing constant accelerations. The corresponding extended Galilean algebra allows, in any dimension , the introduction…
