Prepare inflationary universe via the Euclidean charged wormhole

TL;DR

This paper proposes a model where Euclidean charged wormholes serve as the initial quantum state of the universe, potentially explaining the onset and duration of cosmic inflation.

Contribution

It introduces a new Euclidean charged wormhole configuration as a plausible pre-inflationary initial state, extending previous models with axion wormholes.

Findings

High probability of long inflation from charged wormhole initial state

Comparison shows differences with axion wormhole models

Potential of other Euclidean configurations as initial states

Abstract

In this paper, we present a wavefunction of the universe, which correspond to an Euclidean charged wineglass (half)-wormholes semiclassically, as a possible creation for our inflationary universe. We calculate the Euclidean action of the charged wormhole, and find that the initial state of universe brought by such an Euclidean charged wormhole can exhibit a high probability weight for a long period of inflation. We compare our result with that of axion wormholes, and evaluate the potential of other corresponding Euclidean configurations as the pre-inflationary initial states.
