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…
Boundary effects on classical liquid density fluctuations
K. E. L. de Farias, Azadeh Mohammadi, Herondy F. Santana Mota
In this paper, we study quantum vacuum fluctuation effects on the mass density of a classical liquid arising from the conical topology of an effective idealized cosmic string space…
Scattering cross-section in gravitating cosmic string spacetimes
Marcos Silva, Azadeh Mohammadi
We propose a modification of the partial wave approach to deal with the relativistic quantum scattering of bosonic and fermionic particles in a class of models concerning gravitati…
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…
