Occurrence of tachyonic preheating in the mixed Higgs-R2 model

It has recently been suggested that at the post-inflationary stage of the mixed Higgs-R2 model of inflation efficient particle production can arise from the tachyonic instability of the Higgs field. It might complete the preheating of the Universe if appropriate conditions are satisfied, especially...
