Quintom models, with its Equation of State being able to cross the cosmological constant boundary $w=-1$, turns out to be attractive for phenomenological study. It can not only be applicable for dark energy model for current universe, but also lead to a bounce scenario in the early universe.

  1. Realization of quintom dark energy after DESI DR2 in Nieh-Yan modified teleparallel gravity

    gr-qc 2026-01 conditional novelty 6.0

    Coupling a single fluid or scalar dark energy to the Nieh-Yan density removes its unstable perturbation, allowing a healthy quintom-B crossing and predicting gravitational-wave velocity birefringence.

  2. The Quintom theory of dark energy after DESI DR2

    astro-ph.CO 2025-05 unverdicted novelty 3.0

    This review traces the history of dynamical dark energy, presents the no-go theorem against single-field crossing of w = -1, and surveys viable Quintom constructions including multi-field models and modified gravity i...
