Decoupling perturbations from background in $f (Q)$ gravity: the square-root correction and the impact on the $σ_{8}$ tension

Chunyu Li, Xin Ren, Yuhang Yang +2

We investigate a perturbation-level modification of symmetric teleparallel gravity of the form $f (Q) = F (Q) + M Q$ and assess its potential to ease the $σ_{8}$ tension. The square-…

Quantum Gravity Meets DESI: Dynamical Dark Energy in Light of the Trans-Planckian Censorship Conjecture

Chunyu Li, Junkai Wang, Dongdong Zhang +2

Recent DESI DR2 observations indicate that dark energy has crossed from phantom to quintessence regime, a behavior known as the quintom-B realization. In this work we constrain dyn…

Gaussian-process reconstructions and model building of quintom dark energy from latest cosmological observations

Yuhang Yang, Qingqing Wang, Chunyu Li +4

In this article we use the latest cosmological observations, including SNe, BAO, CC and RSD, to reconstruct the cosmological evolution via the Gaussian process. At the background l…
