Abstract:We present fully non-linear simulations of a self-interacting scalar field in the early universe undergoing tachyonic preheating. We find that density perturbations on subhorizon scales which are amplified by tachyonic instability maintain long range correlations even during the succeeding parametric resonance, in contrast to the predictions from the standard models of preheating dominated by parametric resonance. As a result the final spectrum exhibits memory and is not universal in shape. We find that throug… Show more
“…Formerly, Gevorgyan et al 163 reviewed the same topic regarding the advances in the chemistry of β-aminoketones and published an update in 1985 regarding the chemical reactivity of this type of moiety. In 2008, Simplício et al 164 reviewed the amine prodrugs including the significance of β-aminoketones as the privileged motif of many drugs.…”
The current study highlighted the significance of β-aminoketones as privileged biologically active molecules, recent synthetic strategies, and synthetic applications.
