Abstract

Quintessence models of dark energy are studied as a viable alternative to the cosmological constant and feature an evolving scalar field which dominates the energy budget today causing accelerated expansion. In this chapter we present three stages of N-body simulations of structure formation in quintessence models. Each stage progressively relaxes the assumptions made and brings us closer to a full physical model. In the first stage, the initial conditions for each quintessence cosmology are generated using a \(\Lambda \)CDM linear theory power spectrum and the background cosmological parameters are the best fit values assuming a \(\Lambda \)CDM cosmology.
