Dark energy as a remnant of inflation and electroweak symmetry breaking
Konstantinos Dimopoulos, Tommi Markkanen
It is shown that dark energy can be obtained from the interplay of the Higgs boson and the inflaton. A key element is the realization that electroweak symmetry breaking can trigger…
Primordial Black Hole Formation During Slow Reheating After Inflation
Bernard Carr, Konstantinos Dimopoulos, Charlotte Owen +1
We study the formation of primordial black holes (PBHs) in the early Universe during a period of slow reheating after inflation. We demonstrate how the PBH formation mechanism may…
Instant Preheating in Quintessential Inflation with -Attractors
Konstantinos Dimopoulos, Leonora Donaldson Wood, Charlotte Owen
We investigate a compelling model of quintessential inflation in the context of -attractors, which naturally result in a scalar potential featuring two flat regions, the inflati…
