Folded Inflation, Primordial Tensors, and the Running of the Scalar Spectral Index
Richard Easther
I discuss folded inflation, an inflationary model embedded in a multi-dimensional scalar potential, such as the stringy landscape. During folded inflation, the field point evolves…
Attractive Forces Between Global Monopoles and Domain Walls
Stephon Alexander, Robert Brandenberger, Richard Easther
We study the interaction between stable monopoles and domain walls in a scalar field theory. Numerical simulations reveal that there is an attractive force betw…
Preheating, Parametric Resonance and the Einstein Field Equations
Matthew Parry, Richard Easther
We consider the interaction between perturbations in the inflaton and in the metric during the preheating phase in simple inflationary models. By numerically integrating the Einste…
On the Interaction of Monopoles and Domain Walls
Stephon Alexander, Robert Brandenberger, Richard Easther +1
We study the interaction between monopoles and embedded domain walls in a O(3) linear sigma model. We discover that there is an attractive force between the monopole and the wall.…
Chaos after Two-Field Inflation
Richard Easther
We show that two-field inflation can be followed by an era in which the field dynamics become chaotic, and discuss the possible consequences of this for two-field inflationary mode…
