String Cosmology in the Jackiw-Telteiboim Model with Quantum Corrections

TL;DR

This paper explores how quantum corrections in the Jackiw-Telteiboim model of two-dimensional gravity can lead to non-trivial cosmological solutions, including those with initial singularities, enhancing classical models.

Contribution

It introduces quantum corrections into the Jackiw-Telteiboim model, revealing new cosmological solutions not present in the classical framework.

Findings

Quantum corrections can induce non-trivial cosmological solutions.

Some solutions exhibit initial singularities.

Classical solutions are transformed into more interesting cosmologies.

Abstract

This note deals with the possibility of non-trivial cosmological solutions given by quantum corrections in the framework of the Jackiw-Telteiboim model to the bidimensional gravity. The resulting model shows that the quantum corrections transform, in some cases, the classical solution into a more interesting one with initial singularity.
