Origin of Structure in a Supersymmetric Quantum Universe

TL;DR

This paper extends quantum cosmological models by incorporating supersymmetric inhomogeneous field modes, leading to potential scale-free density perturbation spectra consistent with the no-boundary proposal.

Contribution

It introduces a supersymmetric perturbation framework in quantum cosmology, connecting no-boundary states with inhomogeneous modes.

Findings

Quantum states exhibit properties of the no-boundary proposal.

Model predicts a scale-free spectrum of density perturbations.

Supersymmetric inhomogeneous modes are successfully incorporated.

Abstract

In this report we advance the current repertoire of quantum cosmological models to incorporate inhomogenous field modes in a supersymmetric manner. In particular, we introduce perturbations about a supersymmetric FRW model. A quantum state of our model has properties typical of the no-boundary (Hartle--Hawking) proposal. This solution may then lead to a scale--free spectrum of density perturbations.
