Lukewarm inflation and the QCD axion
Paulo B. Ferraz, António Torres Manso, João G. Rosa
We show that a late period of warm inflation, at temperatures just above the QCD scale, can dilute the abundance of the QCD axion produced by the misalignment mechanism, thus avoid…
Lukewarm inflation, primordial black holes and gravitational waves
Paulo B. Ferraz, António Torres Manso, João G. Rosa
We show that a secondary period of warm inflation, at temperatures parametrically below the GUT scale, may not only dilute any unwanted thermal relics formed after reheating but al…
The inflation trilogy and primordial black holes
Paulo B. Ferraz, João G. Rosa
We propose an inflation scenario with three independent stages of cold, warm and thermal inflation, respectively, driven by different scalar fields, motivated by the large number o…
Shrinking the Warm Little Inflaton
Paulo B. Ferraz, João G. Rosa
We show that warm inflation can be successfully realized in the high temperature regime through dissipative interactions between the inflaton and a single fermionic degree of freed…
