Cosmic Duality in Quintom Universe
Yi-Fu Cai, Hong Li, Yun-Song Piao, Xinmin Zhang
TL;DR
This paper explores the duality in two-field Quintom models of Dark Energy, showing that an expanding universe with one field is dual to a contracting universe with another, revealing new symmetries in cosmic evolution.
Contribution
It introduces a duality framework between different Quintom field configurations, enhancing understanding of dark energy models.
Findings
Expanding Quintom-A universe is dual to contracting Quintom-B universe.
Duality reveals symmetry in cosmic evolution scenarios.
Provides new insights into dark energy dynamics.
Abstract
In this paper we study the duality in two-field Quintom models of Dark Energy. We find that an expanding universe dominated by Quintom-A field is dual to a contracting universe with Quintom-B field.
