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 smooth attachment of various slopes exiting into the final minimum of a realistic potential. Our tunneling solution thus serves as a realistic approximation to situations such as populating a landscape of slow-roll inflationary regions by tunneling, and it is valid for all regimes of the barrier…

A Toy Model For Single Field Open Inflation
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
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
Exact one-loop false vacuum decay rate
We discuss an exact false vacuum decay rate at one loop for a real and complex scalar field in a quartic-quartic potential with two tree-level minima. The bounce solution is used to compute the
Analytic bounces in d dimensions
We study the Euclidean bounce action interpolating between a false and a true vacuum for a scalar field theory with various types of potential. We focus on the cases of a triangular, a square and a
Lower bound for the multifield bounce action
We present a lower bound for the multifield bounce action with a quartic potential with bounded coefficients in the absence of gravity. We find that for a large number of fields the lower bound

Self-excitation of the tunneling scalar field in false vacuum decay.
TLDR
This work investigates in detail the spectrum of quantum excitations of the tunneling field when it undergoes false vacuum decay and finds a strong dependence of the excitation spectrum upon the shape of the potential on the true vacuum side.
False vacuum decay with gravity in the non-thin-wall limit
We consider a wave-function approach to the false vacuum decay with gravity and present a new method to calculate the tunneling amplitude under the WKB approximation. The result agrees with the one

It is possible for a classical field theory to have two homogeneous stable equilibrium states with different energy densities. In the quantum version of the theory, the state of higher energy density
Creation of an Open Universe from Valley Bounce
It appears difficult to construct a simple model for an open universe based on the one bubble inflationary scenario. The reason is that one needs a large mass to avoid the tunneling via the Hawking

It is possible for a classical field theory to have two stable homogeneous ground states, only one of which is an absolute energy minimum. In the quantum version of the theory, the ground state of
Toy model for open inflation
TLDR
This work proposes a simple one-field model where the Coleman-De Luccia instanton does exist and the open inflation scenario can be realized.
