CPT Student Seminar: Massless baby Skyrmions in AdS_3 and extensions to 3+1 dimensions

Presented by Thomas Winyard, Durham University

22 June 2015 17:00 in OC218

Skyrmions are candidates for a solitonic description of nuclei, with the topological charge or number of solitons being identified with the baryon number. I will present work on the 2-dimensional analogue, the baby Skyrme model, in an AdS_3 background. I will demonstrate that stable solutions can be formed with no mass term, due to the addition of the metric and that the numerical solutions now take the form of slightly perturbed concentric rings. I will then propose a simple numerical model, that will allow transitions between the different forms of ring solutions to be predicited. Finally, I will touch upon my current work, on how this extends to the full 3-dimensional Skyrme model in AdS_4. I propose that the results in 2-dimensions suggest that Skyrmions in this space, should take the form of multi-layered concentric rational maps.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
