Dynamics of the topological structures in inhomogeneous media (2008)
Presentation / Conference Contribution
Ferreira, L., Piette, B., & Zakrzewski, W. (2008). Dynamics of the topological structures in inhomogeneous media. In Journal of Physics: Conference Series. The 5th International Symposium on Quantum Theory and Symmetries: 22–28 July 2007, Valladolid, Spain. https://doi.org/10.1088/1742-6596/128/1/012027

We present a general review of the dynamics of topoligical solitons in 1 and 2 dimensions and then discuss some recent work on the scattering of various solitonic objects (such as kinks and breathers etc) on potential obstructions.

Wobbles and other kink-breather solutions of the Sine Gordon model (2008)
Journal Article

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 in a recent paper by Kälberman, is one of such solutions. We concentrate ou...

Skyrme Model with Different Mass Terms (2008)

We consider a one parameter family of mass terms for the Skyrme model that disfavors shell-like configurations for multibaryon classical solutions. We argue that a model with such mass terms can provide a better description of nuclei as shell-like co... Read More about Skyrme Model with Different Mass Terms.

Effects of Periodic electromagnetic Field on Charge Transport in Macromolecules (2008)
Presentation / Conference Contribution
Macromolecules

We study effects of periodic fields on charge transport in macromolecules and show that solitons acquire complex dynamics induced by the interplay between the periodic in time external field, energy dissipation, and depends on the molecule symmetry....

Scattering of sine-Gordon Kinks and Breathers on a Finite Width Well (2008)
Presentation / Conference Contribution
Well.

We analyse the scattering of sine-Gordon kinks and breathers on a square potential well. We show that when a kink is sent onto the well, it can go through it, be trapped, or sometimes even bounce back out of the well. For breathers, the situation is...

Ratchet behaviour of polarons in molecular chains (2008)
Journal Article

We study the ratchet behaviour of polarons in diatomic molecular chains under the influence of an external electromagnetic field which is periodic in time. We show that in asymmetric chains a harmonic unbiased field causes a drift of polarons. This p... Read More about Ratchet behaviour of polarons in molecular chains.
