Fermionic spectral walls in kink collisions
João G. F. Campos, Azadeh Mohammadi, Jose M. Queiruga +2
We show that a spectral wall, i.e., an obstacle in the dynamics of a bosonic soliton, which arises due to the transition of a normal mode into the continuum spectrum, exists after…
Resonance mediated by fermions in kink-antikink collisions
Dionisio Bazeia, João G. F. Campos, Azadeh Mohammadi
We investigate generalizations of the and sine-Gordon models, including interactions with Dirac Fermions. We observe new resonance phenomena by taking the fermion back-reacti…
Kink-antikink collision in the supersymmetric model
João G. F. Campos, Azadeh Mohammadi
This paper investigates a model containing kinks interacting with fermions. The fermion back-reaction is included in the equations of motion, which affects the kink-antikink…
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…
