Hartree approximation in curved spacetimes revisited II: The semiclassical Einstein equations and de Sitter self-consistent solutions

Diana L. López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta

We consider the semiclassical Einstein equations (SEE) in the presence of a quantum scalar field with self-interaction $\lambda {\varphi }^4$. Working in the Hartree truncation of the two-particle…
