Título:
Dynamical vibrational moduli space in soliton dynamics
Coloquialista:
Andrzej Wereszczynski
Jagiellonian University, Krakow, Poland
Resumo:
I will describe how the collective coordinate models i.e., the moduli space (MS) approximation, allows us to understand complicated multi-soliton collisions. Specifically, I will show how a frozen vibrational MS captures the kink-antikink collision in the \phi^4 model. Then, I will focus on a dynamical version of the vibrational MS, where its collapse, due to a singularity formation, has an important physical meaning explaining the so-called spectral walls.
