Interactions between topological defects in (1+1) dimensions
João G. F. Campos
In this thesis, we study interactions between topological defects in two-dimensional spacetimes. These defects are called kinks. They are solutions of scalar field theories with lo…
Fermions on wobbling kinks: normal versus quasinormal modes
João G. F. Campos, Azadeh Mohammadi
The system consisting of a fermion in the background of a wobbling kink is studied in this paper. To investigate the impact of the wobbling on the fermion-kink interaction, we empl…
Wobbling double sine-Gordon kinks
João G. F. Campos, Azadeh Mohammadi
We study the collision of a kink and an antikink in the double sine-Gordon model with and without the excited vibrational mode. In the latter case, we find that there is a limited…
Fermion transfer in the model with a half-BPS preserving impurity
João G. F. Campos, Azadeh Mohammadi
We study a fermion field coupled to a scalar via a Yukawa term. The scalar field is the model with an impurity that preserves half of the BPS property. We analyze the spectru…
Stochastic oscillations produce dragon king avalanches in self-organized quasi-critical systems
O. Kinouchi, L. Brochini, A. A. Costa +2
In the last decade, several models with network adaptive mechanisms (link deletion-creation, dynamic synapses, dynamic gains) have been proposed as examples of self-organized criti…
