Phys. Rev. D 66, 023524 (2002) [6 pages]Initial conditions for quintessence after inflationReceived 15 March 2002; revised 17 May 2002; published 30 July 2002 We consider the behavior of a quintessence field during an inflationary epoch, in order to learn how inflation influences the likely initial conditions for quintessence. We use the stochastic inflation formalism to study quantum fluctuations induced in the quintessence field during the early stages of inflation, and conclude that these drive its mean to large values (≳0.1mPl). Consequently we find that tracker behavior typically starts at low redshift, long after nucleosynthesis and most likely also after decoupling. © 2002 The American Physical Society URL:
