Creation of a scalar potential in 2D dilaton gravity

TL;DR

This paper studies quantum effects in 2D dilaton gravity, showing that quantum corrections can remove classical singularities by generating a scalar potential, with implications for cosmological models.

Contribution

It demonstrates that quantum corrections in 2D dilaton gravity can eliminate singularities by creating a scalar potential, a novel insight into quantum gravity effects.

Findings

Singularity disappears due to quantum corrections.

A scalar potential for dilaton/moduli is generated.

Quantum effects alter classical cosmological solutions.

Abstract

We investigate quantum corrections of the 2-d dilaton gravity near the singularity. Our motivation comes from a s-wave reduced cosmological solution which is classically singular in the scalar fields (dilaton and moduli). As result we find, that the singularity disappears and a dilaton/moduli potential is created.
