Nonperturbative Corrections to Particle Production from Coherent Oscillation
Nonperturbative Corrections to Particle Production from Coherent Oscillation
We investigate particle production from coherent oscillation by using the method based on the Bogolyubov transformation.Especially, we study the case when the amplitude of the oscillation and also the coupling constants with the oscillating field are small in order to avoid the non-perturbative corrections from the broad parametric resonance.We derive …
