DESCRIPTION:Speakers: Duvier Fontanella (ICIMAF)\nWe present the state of
research devoted to investigate the consequences of a formerly proposed re
gular solution at the origin for the Einstein-Klein-Gordon equations. We i
mplement a match with the Schwarzschild solutions with a zero scalar field
outside a spherical region. The configuration of fields are used as a fir
st step in an iterative process to calculate the vacuum expectation value
of the energy-momentum tensor\, aiming at further solving the Einstein sem
i-classical equation. The result shows the quantum corrections to the prev
ious solution. It is expected that further steps in the iterative process
will regulate the previous solutions\, by leading to the convergence of th
e iterative solution. The first step in the iteration solution and an expl
icit dependence of the expectation value of the energy-momentum tensor wit
h the metric are found.\n\nhttps://indico.cern.ch/event/721602/contributio
