The Hartree approximation in curved spacetimes revisited I: the effective potential in de Sitter

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

We consider a quantum scalar field with λϕ^4 interaction in curved spacetimes. The quantum effects are taken into account nonperturbatively using the Hartree approximation to the 2…
