Abstract

The evolution of the quintessence field during a phase of chaotic inflation is studied. The inflaton \ensuremathφ and the quintesssence field Q are described in a supergravity framework where the coupling between the inflaton and quintessence is induced by nonrenormalizable operators suppressed by the Planck mass. We show that the resulting quintessence potential during inflation possesses a time-dependent minimum playing the role of an attractor. The presence of this attractor forces the quintessence field to be small during inflation. These initial conditions are such that the quintessence field is on track now.
