Birth of the Universe as anti-tunnelling from the string perturbative vacuum

TL;DR

This paper proposes a quantum cosmology model where the universe's birth results from an anti-tunneling process driven by string theory dynamics, involving vacuum decay and wave function amplification.

Contribution

It introduces a novel mechanism for universe creation via vacuum decay in string theory, highlighting the role of dilaton potential and wave function amplification.

Findings

Vacuum decay can trigger universe creation through anti-tunneling.

Wave function amplification facilitates the birth of the universe.

The model aligns with quantum pair production from the vacuum.

Abstract

The decay of the string perturbative vacuum, if triggered by a suitable, duality-breaking dilaton potential, can efficiently proceed via the parametric amplification of the Wheeler-De Witt wave function in superspace, and can appropriately describe the birth of our Universe as a quantum process of pair production from the vacuum.
