Determination of cosmic curvature independent of the sound horizon and using BOSS/eBOSS and DESI DR1 BAO observations
Tonghua Liu, Shengjia Wang, Hengyu Wu +1
We present an improved model-independent method for determining the cosmic curvature using the observations of Baryon Acoustic Oscillations (BAOs) and the Hubble parameter. The pur…
A model-independent determination of the sound horizon using recent BAO measurements and strong lensing systems
Tonghua Liu, Shuo Cao, Jieci Wang
We propose an improved method to determine the sound horizon in a cosmological model-independent way by using the latest observations of BAO measurements from DES, BOSS/eBOSS, and…
Model independent calibration for sound horizon combining observations of supernovae and transversal BAO measurements
Tonghua Liu, Xinyi Zhong, Jieci Wang +1
The sound horizon is a key theoretical prediction of the cosmological model that depends on the speed of sound and the rate of expansion in the early universe, before matter and ra…
Optimal quantum strategy for locating Unruh channels
Qianqian Liu, Tonghua Liu, Cuihong Wen +1
From the perspective of quantum information theory, the effect of Unruh radiation on a two-level accelerated detector can be modeled as a quantum channel. In this work, we employ t…
