Scalar cosmological perturbation in an inflationary brane world driven by the bulk inflaton
Da-Ping Du, Bin Wang, Elcio Abdalla +1
We investigate scalar perturbations from inflation in a bulk inflaton braneworld model. Using the generalized longitudinal gauge, we derive and solve the full set of scalar perturb…
WMAP constraint on the P-term inflationary model
Bin Wang, Chi-Yong Lin, Elcio Abdalla
In light of WMAP results, we examine the observational constraint on the P-term inflation. With the tunable parameter , P-term inflation contains richer physics than D-term and…
A plausible upper limit on the number of e-foldings
Bin Wang, Elcio Abdalla
Based solely on the arguments relating Friedmann equation and the Cardy formula we derive a bound for the number of e-folds during inflation for a standard Friedmann-Robertson-Walk…
Numerical simulation of Quasi-Normal Modes in time-dependent background
Li-Hui Xue, Zai-Xiong Shen, Bin Wang +1
We study the massless scalar wave propagation in the time-dependent Schwarzschild black hole background. We find that the Kruskal coordinate is an appropriate framework to investig…
Modification to the power spectrum in the brane world inflation driven by the bulk inflaton
Bin Wang, Li-Hui Xue, Xinmin Zhang +1
We compute the cosmological perturbations generated in the brane world inflation driven by the bulk inflaton. Different from the model that the inflation is a brane effect, we exhi…
