Nonrelativistic Dark-Energy Fluid in a Baby Universe
P. C. Stichel, W. J. Zakrzewski
We show that the dynamical realization of the acceleration-enlarged Galilean symmetry leads to nonrelativistic massless particles whose energy may be negative. We present a fluid m…
Some properties of deformed Sine Gordon models
Akmaral Alibek, Ratbay Myrzakulov, W. J. Zakrzewski
We study some properties of the deformed Sine Gordon models. These models, presented by Bazeia et al, are natural generalisations of the Sine Gordon models in (1+1) dimensions. The…
Scattering of Topological Solitons on Barriers and Holes of Deformed Sine-Gordon Models
Jassem H. Al-Alawi, Wojtek J. Zakrzewski
We study scattering properties of topological solitons in two classes of models, which are generalizations of the Sine-Gordon model and which have recently been proposed by Bazeia…
Skyrme Model with Different Mass Terms
Bernard Piette, Wojtek J. Zakrzewski
We consider a one parameter family of mass terms for the Skyrme model that disfavours shell-like configurations for multi-baryon classical solutions. We argue that a model with suc…
