Cosmological-model-independent tests for the distance-duality relation from Galaxy Clusters and Type Ia Supernova

Zhengxiang Li, Puxun Wu, Hongwei Yu

We perform a cosmological-model-independent test for the distance-duality (DD) relation $η (z) = D_{L} (z) (1 + z)^{- 2} / D_{A} (z)$ , where $D_{L}$ and $D_{A}$ are the luminosity distance and angula…

Open quantum system approach to Gibbons-Hawking effect of de Sitter space-time

Hongwei Yu

We analyze, in the paradigm of open quantum systems, the reduced dynamics of a freely-falling two-level detector in de Sitter space-time in weak interaction with a reservoir of flu…
