Model-independent constraints on cosmic curvature: implication from the future gravitational wave observation DECIGO

Xiaogang Zheng, Shuo Cao, Yuting Liu +5

A model-independent test of the cosmic curvature parameter is very important in cosmology. In order to estimate cosmic curvature from cosmological probes like standard candle…

A model-independent constraint on the Hubble constant with gravitational waves from the Einstein Telescope

Sixuan Zhang, Shuo Cao, Jia Zhang +4

In this paper, we investigate the expected constraints on the Hubble constant from the gravitational-wave standard sirens, in a cosmological-model-independent way. In the framework…

Model-independent constraints on cosmic curvature: implication from updated Hubble diagram of high-redshift standard candles

Yuting Liu, Shuo Cao, Tonghua Liu +4

The cosmic curvature () is a fundamental parameter for cosmology. In this paper, we propose an improved model-independent method to constrain the cosmic curvature, which is ge…

Testing the cosmic opacity at higher redshifts: implication from quasars with available UV and X-ray observations

Tonghua Liu, Shuo Cao, Marek Biesiada +3

In this paper, we present a cosmological model-independent test for the cosmic opacity at high redshifts (). We achieve this with the opacity-dependent luminosity distances…

Testing the cosmic curvature at high redshifts: the combination of LSST strong lensing systems and quasars as new standard candles

Tonghua Liu, Shuo Cao, Jia Zhang +3

The cosmic curvature, a fundamental parameter for cosmology could hold deep clues to inflation and cosmic origins. We propose an improved model-independent method to constrain the…

Quantum fluctuation of entanglement for accelerated two-level detectors

Sixuan Zhang, Tonghua Liu, Shuo Cao +3

Quantum entanglement as the one of the most general quantum resources, can be quantified by von Neumann entropy. However, as we know, the von Neumann entropy is only statistical qu…
