Abstract
In this work quantum corrections to the classical evolution of a relativistic scalar condensate are studied. The problem is approached by means of two different perturbative approaches: the 2-particle-irreducible (2PI) effective action and the expansion in the self-coupling. In the weak coupling regime the decoherence of the classical state is observed. The corresponding timescale is identified with the quantum break-time.
