TL;DR

This paper uses a genetic algorithm to find stable vacua in non-geometric flux compactifications, revealing that multiple stable de Sitter and Anti-de Sitter vacua support slow-roll inflation driven by axio-dilaton and Kähler moduli.

Contribution

It introduces a genetic algorithm approach to identify stable vacua in non-geometric flux compactifications, demonstrating the viability of slow-roll inflation in these models.

Findings

Equal number of stable dS and AdS vacua found.

All dS vacua support multi-field slow-roll inflation.

Inflation driven by axio-dilaton and Kähler moduli.

Abstract

By implementing a genetic algorithm we search for stable vacua in Type IIB non-geometric flux compactification on an isotropic torus with orientifold 3-planes. We find that the number of stable dS and AdS vacua are of the same order. Moreover we find that in all dS vacua the multi-field slow-roll inflationary conditions are fulfilled. Specifically we observe that inflation is driven by the axio-dilaton and the K\"ahler moduli. We also comment on the existence of one stable dS vacuum in the presence of exotic orientifolds.
