Topological Solitons Seminar: QBalls, integrability and Duality

Presented by David Foster, University of Durham

18 November 2008 14:15 in CM219

The basis of this talk shall be drawn from our paper "QBall, Integrability and Duality". I'll be discussing the dynamics of interacting (1+1)-dimension QBalls. Firstly discussing the asymptotic force between two well-separated QBalls. Outlining how the integrable Complex-Sine Gordon solitons are QBalls solutions. This is then used to understand the semi-integrable nature of small charge QBalls and the breather like modes of perturbed QBalls. Finally then showing that any QBall theory has a dual description as a static kink with topological charge.
