Topological Solitons Seminar: Narcissistic Skyrmions
14 March 2011 16:15 in CM221
The Skyrme model is a nonlinear sigma-model whose topologically non-trivial target space allows the possibility of topological solitons. Such solitons were proposed by Skyrme to model nuclear matter. In this talk I will briefly review the model and present recent work with Gary Gibbons and Willie Wong ruling out the existence of solitons admitting certain symmetries. I will also indicate how the method can be extended to related models.
