Collision of two kinks with inner structure
Yuan Zhong, Xiao-Long Du, Zhou-Chao Jiang +2
In this work, we study kink collisions in a scalar field model with scalar-kinetic coupling. This model supports kink/antikink solutions with inner structure in the energy density.…
Scalar perturbations of Eddington-inspired Born-Infeld braneworld
Ke Yang, Yu-Xiao Liu, Bin Guo +1
We consider the scalar perturbations of Eddington-inspired Born-Infeld braneworld models in this paper. The dynamical equation for the physical propagating degree of freedom $ξ(x^μ…
Large Scale Structure Formation in Eddington-inspired Born-Infeld Gravity
Xiao-Long Du, Ke Yang, Xin-He Meng +1
We study the large scale structure formation in Eddington-inspired Born-Infeld (EiBI) gravity. It is found that the linear growth of scalar perturbations in EiBI gravity deviates f…
Dirac dynamical resonance states around Schwarzschild black holes
Xiang-Nan Zhou, Xiao-Long Du, Ke Yang +1
Recently, a novel kind of scalar wigs around Schwarzschild black holes---scalar dynamical resonance states were introduced in [Phys. Rev. D 84, 083008 (2011)] and [Phys. Rev. Lett.…
Linear perturbations in Eddington-inspired Born-Infeld gravity
Ke Yang, Xiao-Long Du, Yu-Xiao Liu
We study the full linear perturbations of a homogeneous and isotropic spacetime in the Eddington-inspired Born-Infeld gravity. The stability of the perturbations are analyzed in th…
Gravity localization and mass hierarchy in scalar-tensor branes
Ke Yang, Yu-Xiao Liu, Yuan Zhong +2
We consider a braneworld model in the scalar-tensor gravity. In order to solve the gauge hierarchy problem in this model, our world should be confined on the positive tension brane…
