A Toy Model For Single Field Open Inflation

  title={A Toy Model For Single Field Open Inflation},
  author={Pascal M. Vaudrevange and Alexander Westphal},
  journal={arXiv: High Energy Physics - Theory},
Inflation in an open universe produced by Coleman-De Luccia (CDL) tunneling induces a friction term that is strong enough to allow for successful small-field inflation in models that would otherwise suffer from a severe overshoot problem. In this paper, we present a polynomial scalar potential which allows for a full analysis. This provides a simple model of single-field open inflation on a small-field inflection point after tunneling. We present numerical results and compare them with analytic…

Scalar suppression on large scales in open inflation
We consider two toy models of open inflation and investigate their ability to give a suppression of scalar power on large scales while also satisfying observational constraints on the spatial
Accidental Inflation in the Landscape
We study some aspects of fine tuning in inflationary scenarios within string theory flux compactifications and, in particular, in models of accidental inflation. We investigate the possibility that
Probability of Slowroll Inflation in the Multiverse
It is shown that the FVEI picture is still self-consistent and may have a strong preference between different slowroll models and the chance to slowroll is exponentially suppressed, where the exponent comes from the number of fields.
Nonlinear Intermittent Field Dynamics in the Early Universe
We explore nonequilibrium dynamics of inhomogeneous nonlinearly interacting scalar fields in several cosmological settings. In particular, we explore the effects of (initially small) asymmetric
Accidental Ination in the Landscape
We study some aspects of ne tuning in inationary scenarios within string theory ux compactications and, in particular, in models of accidental ination. We investigate the possibility that the


Toy model for open inflation
This work proposes a simple one-field model where the Coleman-De Luccia instanton does exist and the open inflation scenario can be realized.
Advances in Inflation in String Theory
We provide a pedagogical overview of inflation in string theory. We focus upon the sensitivity of inflation to Planck-scale physics, which we argue provides both the primary motivation and the
Multi-field open inflation model and multi-field dynamics in tunneling
We consider a multi-field open inflation model, in which one of the fields dominates quantum tunneling from a false vacuum while the other field governs slow-roll inflation within the bubble
New old inflation
We propose a new class of inflationary solutions to the standard cosmological problems (horizon, flatness, monopole,...), based on a modification of old inflation. These models do not require a
The overshoot problem in inflation after tunneling
We show the absence of the usual parametrically large overshoot problem of small-field inflation if initiated by a Coleman-De Luccia (CDL) tunneling transition from an earlier vacuum in the limit of
Accidental inflation in string theory
We show that inflation in type IIB string theory driven by the volume modulus can be realized in the context of the racetrack-based Kallosh–Linde model (KL) of moduli stabilization. Inflation here
Universality in D-brane inflation
We study the six-field dynamics of D3-brane inflation for a general scalar potential on the conifold, finding simple, universal behavior. We numerically evolve the equations of motion for an ensemble
An exact tunneling solution in a simple realistic landscape
We present an analytical solution for the tunneling process in a piecewise linear and quadratic potential which does not make use of the thin-wall approximation. A quadratic potential allows for the
Open inflation in the landscape
Open inflation scenario is attracting a renewed interest in the context of string landscape. Since there are a large number of metastable de Sitter vacua in string landscape, tunneling transitions to
