DESCRIPTION:After a period of inflation the density of the universe is neg
 ligible. The process by which it fills up again with particles and radiati
 on is called reheating. In chaotic inflation reheating occurs through the 
 coupling of quantum fields with the inflaton field (possibly including a c
 oupling of the inflaton field with itself). The energy for the creation of
  the particles comes from the inflaton field. In many cases the particle p
 roduction is extremely rapid due to the process of parametric amplificatio
 n. Some interesting issues regarding parametric amplification will be disc
 ussed including the question of whether a quantum field theory is renormal
 izable when parametric amplification occurs\, what effects the process has
  on the inflaton field\, and whether all of the energy of the inflaton fie
 ld is dissipated by this process.\n\nhttps://indico.ific.uv.es/event/1535/
