Complex scalar field thick branes: stability of linear perturbation and evolution of scalar Kaluza-Klein modes coupled with gravity
Wang-Long Dong, Heng Guo, Qun Wei +1
We investigate the stability and localization properties of Minkowski, de Sitter (dS), and anti-de Sitter (AdS) thick branes generated by a complex scalar field . The scalar sel…

Two-scalar-field 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 gravity supported by two-scalar-field. The two-scalar sector provides an analytical warped background with tunable energy…
