The dynamics of aloof baby Skyrmions
Petja Salmi, Paul Sutcliffe
The aloof baby Skyrme model is a (2+1)-dimensional theory with solitons that are lightly bound. It is a low-dimensional analogue of a similar Skyrme model in (3+1)-dimensions, wher…
Aloof Baby Skyrmions
Petja Salmi, Paul Sutcliffe
We show that a suitable choice for the potential term in the two-dimensional baby Skyrme model yields solitons that have a short-range repulsion and a long-range attraction. The so…
Radiation and Relaxation of Oscillons
Petja Salmi, Mark Hindmarsh
We study oscillons, extremely long-lived localized oscillations of a scalar field, with three different potentials: quartic, sine-Gordon model and in a new class of convex potentia…
Oscillons and Domain Walls
Mark Hindmarsh, Petja Salmi
Oscillons, extremely long-lived localized oscillations of a scalar field, are shown to be produced by evolving domain wall networks in quartic theory in two spatial dimensions. We…
Kinematic Constraints on Formation of Bound States of Cosmic Strings - Field Theoretical Approach
P. Salmi, A. Achucarro, E. J. Copeland +3
Superstring theory predicts the potential formation of string networks with bound states ending in junctions. Kinematic constraints for junction formation have been derived within…
Numerical Investigations of Oscillons in 2 Dimensions
Mark Hindmarsh, Petja Salmi
Oscillons, extremely long-living localized oscillations of a scalar field, are studied in theories with quartic and sine-Gordon potentials in two spatial dimensions. We present qua…
