Completely Dark Matter from Rapid-Turn Multifield Inflation
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study cosmological gravitational particle production as applied to "rapid-turn" models of inflation involving two scalar fields. We are interested in the production of massive s…
The Gravitino Swampland Conjecture
Edward W. Kolb, Andrew J. Long, Evan McDonough
We extend the swampland from effective field theories (EFTs) inconsistent with quantum gravity to EFTs inconsistent with quantum supergravity. This enlarges the swampland to includ…
Catastrophic Production of Slow Gravitinos
Edward W. Kolb, Andrew J. Long, Evan McDonough
We study gravitational particle production of the massive spin- Rarita-Schwinger field, and its close relative, the gravitino, in FRW cosmological spacetimes. For masses light…
Primordial inflation explains why the universe is accelerating today
Edward W. Kolb, Sabino Matarrese, Alessio Notari +1
We propose an explanation for the present accelerated expansion of the universe that does not invoke dark energy or a modification of gravity and is firmly rooted in inflationary c…
