Motivated by the recent work on the fermion resonances on scalar-constructed thick branes (arXiv:0901.3543 and arXiv:0904.1785), we extend the idea to multi-scalar generated thick branes and complete previous work. The fermion localization…
A toy model where a massless, real, scalar field $\Phi$ in a compact space-time ${\cal M}_4 \times {\cal S}_1$ is coupled to a brane (parametrized as a $\delta$-function) through the unique relevant operator $\delta (y) \Phi^2 (x,y)$ is…

The general procedure for analyzing the localization of matter fields in Brane models is by integrating, in the action, its zero mode solutions over the extra dimensions. If this is finite, the field is said to be localized. However, the…
A Randall-Sundrum type brane-cosmological model in which slow-roll inflation on the brane is driven solely by a bulk scalar field was recently proposed by Himemoto and Sasaki. We analyze their model in detail and calculate the quantum…
