Generalized surface tension bounds in vacuum decay
Ali Masoumi, Sonia Paban, Erick J. Weinberg
Coleman and De Luccia (CDL) showed that gravitational effects can prevent the decay by bubble nucleation of a Minkowski or AdS false vacuum. In their thin-wall approximation this h…
Tunneling from a Minkowski vacuum to an AdS vacuum: A new thin-wall regime
Ali Masoumi, Sonia Paban, Erick J. Weinberg
Using numerical and analytic methods, we study quantum tunneling from a Minkowski false vacuum to an anti-de Sitter true vacuum. Scanning the parameter space of theories with quart…
Negative modes of Coleman-De Luccia bounces
Hakjoon Lee, Erick J. Weinberg
We investigate the negative modes about Coleman-De Luccia bounces governing vacuum transitions in de Sitter space, with the goal of gaining physical insight into the various anomal…
Tumbling through a landscape: Evidence of instabilities in high-dimensional moduli spaces
Brian Greene, David Kagan, Ali Masoumi +3
We argue that a generic instability afflicts vacua that arise in theories whose moduli space has large dimension. Specifically, by studying theories with multiple scalar fields we…
Bounces with O(3) x O(2) symmetry
Ali Masoumi, Erick J. Weinberg
We study the contribution to the decay of de Sitter vacua from bounces with O(3) x O(2) symmetry. These correspond to the thermal production of a vacuum bubble at the center of a h…
Interactions of massless monopole clouds
Christopher M. Miller, Erick J. Weinberg
Some spontaneously broken gauge theories with unbroken non-Abelian gauge groups contain massless magnetic monopoles that are realized classically as clouds of non-Abelian field sur…
