Third Order Density Perturbation and One-loop Power Spectrum in a Dark Energy Dominated Universe
We investigate the third-order density perturbation and the one-loop correction to the linear power spectrum in the dark energy cosmological model. Our main interest is to understand the dark energy effect on the baryon acoustic oscillation in quasi-nonlinear regime (k ≈ 0.1h/Mpc). Analytical solutions and simple fitting formulae are presented for the dark energy model with the general time var...

We investigate the third-order density perturbation and the one-loop correction to the linear power spectrum in the dark-energy cosmological model. Our main interest is to understand the dark-energy effect on baryon acoustic oscillations in a quasi-nonlinear regime (k ≈ 0.1h/Mpc).

متن کاملExact analytic solution of sub - horizon scales linear perturbation for general dark energy models
Three decades ago Heath found the integral form of the exact analytic growing mode solution of linear density perturbation δ in subhorizon scales including the cosmological constant or the curvature term. Interestingly, we are able to obtain the analytic solution for general dark energy models with the constant equation of state ωde. We compare the correct analytic growing mode solution δ with ...
متن کاملGrowth index with the exact analytic solution of sub-horizon scale linear perturbation for general dark energy models
Three decades ago Heath found the integral form of the exact analytic growing mode solution of the linear density perturbation δ on sub-horizon scales including the cosmological constant or the curvature term. Recently, we obtained the exact analytic form of this solution in our previous work [1]. Interestingly, we are able to extend this solution for general dark energy models with the constan...
متن کاملThe Density Perturbation Power Spectrum to Second-Order Corrections in the Slow-Roll Expansion
We set up a formalism that can be used to calculate the power spectrum of the curvature perturbations produced during inflation up to arbitrary order in the slowroll expansion, and explicitly calculate the power spectrum and spectral index up to second-order corrections.
