Quantum Slow Roll
André Benevides, Atish Dabholkar
We consider a scalar field coupled to massless fermions through Yukawa couplings, such as the Higgs field, in a Robertson-Walker spacetime. We compute the nonlocal quantum effectiv…

Nonlocal Quantum Effective Actions in Weyl-Flat Spacetimes
Teresa Bautista, André Benevides, Atish Dabholkar
Virtual massless particles in quantum loops lead to nonlocal effects which can have interesting consequences, for example, for primordial magnetogenesis in cosmology or for computi…

Quantum Cosmology in Four Dimensions
Teresa Bautista, André Benevides, Atish Dabholkar +1
We analyze the cosmological solutions to the recently proposed nonlocal quantum effective action for gravity with a cosmological term. We show that the vacuum energy decays with a…
