Scientific paper

We present a matching procedure for rapidly calculating the non-linear mass power spectrum in dynamical dark energy cosmologies to percent level accuracy in the range of scales between 0.1 < k < 3. This procedure is verified by large N-body simulations and is valid at any redshift for cosmologies consistent with current observations. Such accuracy in the power spectrum is necessary for next generation cosmological mass probes. Our matching procedure reproduces the CMB distance to last scattering and delivers sub-percent level accuracy in the matter power spectra at z = 0 and z ≈ 3. We discuss the physical implications for probing dark energy with surveys of large scale structure.
