Názov: Kinks and oscillons in mechanized models of scalar field theory
Termín: 15.2.2022, 14:00 hod., Google Meet
We propose a systematic way of exploring phenomena of scalar field theories in (1+1)-dimensions, namely kinks, oscillons and their various scattering and decay states. We call this procedure a ‘mechanization’ – the field is replaced by fixed number of joints connected by straight edges. The mechanization is a sequence of general purpose collective coordinate models that approaches the continous field theory as the number of joints goes to infinity. We illustrate the dynamics of ‘mech-kinks’ and ‘mech-oscillons’ and draw a connection between the life-time of oscillons and the bouncing phenomenon in scattering of kink and anti-kink.
