Resumen de To bake matter, first preheat the universe
John Giblin of Kenyon College in Gambier OH and his student J. Tate Deskins have produced the most efficient preheating model yet by finding a way to couple the inflaton to the electromagnetic field. This dumps energy directly into photons. Their simulations show that the inflaton field could deposit 96% of its energy into photons this way. That's enough to ensure that the early universe is dominated by radiation, as predicted, says Giblin.
