We review some recent work on the construction of SU (N) skyrmions from rational, and more generally harmonic, maps from the two-sphere into complex projective spaces. We first describe the SU (2) case, where the rational map approximation is relativ... Read More about Skyrmions from Harmonic Maps..

Some Aspects of Soliton Unwindings. (1996)
Book Chapter
Piette, B., & Zakrzewski, W. (1996). Some Aspects of Soliton Unwindings. In B. Jancewicz, & J. Sobczyk (Eds.), From Field Theory to Quantum Groups: birthday volume dedicated to Jerzy Lukierski (275-285). World Scientific Publishing. https://doi.org/10.1142/9789812830425_0018

We investigate the unwindings of solitons as seen in many numerical simulations. We study a simple model in (2+1) dimensions which involves two scalar fields ø1, ø2 with an interaction term which favours the fields to lie on a unit circle (i.e. to sa...

Classical and Quantum Mechanics of Free κ-Relativistic Systems. (1995)
Book Chapter
Zakrzewski, W., Lukierski, J., & Ruegg, H. (1995). Classical and Quantum Mechanics of Free κ-Relativistic Systems. In J. Lukierski, Z. Popowicz, & J. Sobczyk (Eds.), Quantum groups : formalism and applications : XXX Karpacz Winter School of Theoretical Physics, Karpacz, Poland, 14-26 February 1994 (539-554). Polish Scientific Publishers

We consider the Hamiltonian and Lagrangian formalism describing free κ-relativistic particles with their four-momenta constrained to the κ-deformed mass shell. We study the formalism with commuting as well as noncommuting (i.e., with nonvanishing Poi... Read More about Classical and Quantum Mechanics of Free κ-Relativistic Systems..
