Cyclic completion of the anamorphic universe

TL;DR

This paper demonstrates how the recently proposed anamorphic universe scenario can be extended into a cyclic model using a stable, non-singular bounce, offering an alternative to ekpyrotic cyclic models.

Contribution

It introduces a novel cyclic anamorphic universe model by adapting a stable bounce mechanism, expanding the class of cyclic cosmologies beyond ekpyrotic models.

Findings

Cyclic anamorphic models can be constructed with stable bounces.

The bounce connects contraction and anamorphic smoothing phases.

The approach generalizes bounce mechanisms to new cosmological scenarios.

Abstract

Cyclic models of the universe have the advantage of avoiding initial conditions problems related to postulating any sort of beginning in time. To date, the only known viable examples of cyclic models have been ekpyrotic. In this paper, we show that the recently proposed anamorphic scenario can also be made cyclic. The key to the cyclic completion is a classically stable, non-singular bounce. Remarkably, even though the bounce construction was originally developed to connect a period of contraction with a period of expansion both described by Einstein gravity, we show here that it can naturally be modified to connect an ordinary contracting phase described by Einstein gravity with a phase of anamorphic smoothing. The paper will present the basic principles and steps in constructing cyclic anamorphic models.
