Weak Lensing Constraints on Dark Matter-Baryon Interactions with -Body Simulations and Machine Learning
Chi Zhang, Lei Zu, Hou-Zun Chen +2
We investigate the elastic scattering cross section between dark matter and protons using the DES Year 3 weak lensing data. This scattering induces a dark acoustic oscillation stru…

Mirror QCD phase transition as the origin of the nanohertz Stochastic Gravitational-Wave Background
Lei Zu, Chi Zhang, Yao-Yu Li +3
Several Pulsar Timing Array (PTA) collaborations have recently provided strong evidence for a nHz Stochastic Gravitational-Wave Background (SGWB). Here we investigate the implicati…

Gravity-induced entanglement between two massive microscopic particles in curved spacetime: I.The Schwarzschild background
Chi Zhang, Fu-Wen Shu
The experiment involving the entanglement of two massive particles through gravitational fields has been devised to discern the quantum attributes of gravity. In this paper, we pre…
