Two-scalar-field $f(R)$ Thick Branes, Gravitational Resonances and Quasinormal Modes

Xin-Yi Pan, Heng Guo, Jing-Xin Gong +1

In this paper, we investigate thick brane worlds in $f(R)$ gravity supported by two-scalar-field. The two-scalar sector provides an analytical warped background with tunable energy…
