Renormalization group and spectra of the generalized Pöschl-Teller potential
Ulysses Camara da Silva, Andre Alves Lima, Carlos F. S. Pereira
We study the Pöschl-Teller potential , for every value of the dimensionless parameters and , including the less u…
Collective coordinates for the hybrid model
C. F. S. Pereira, Etevaldo dos Santos Costa Filho, T. Tassis
In the present work, we carry out the study of scattering solitons for the anti-kink/kink and kink/anti-kink configurations. Furthermore, we can observe the same effects as those d…
Some novel considerations about the collective coordinates approximation for the scattering of kinks
Carlos F. S. Pereira, Gabriel Luchini, Tadeu Tassis +1
The collective coordinates approximation for the kink/anti-kink scattering in the dimensional model is considered and we discuss how the results found in the current li…
Real scalar field kink(-antikink)s and their perturbation spectra in a closed universe
Betti Hartmann, Gabriel Luchini, Clisthenis P. Constantinidis +1
In this paper we demonstrate that solitons of a simple real scalar field model that are {\it static and linearly stable} do exist when considered in a (3+1)-dimensional, spatially…
