Searching for Solar-Basin Axionlike-Particle Decay with XMM-Newton Blank-Sky Observations
Bo Zhang, Chi Zhang, Lei Lei +4
Axion-like particles (ALPs) bound in the solar gravitational field form the so-called ALP solar-basin. Since the two-photon decay of non-relativistic particles is approximately iso…

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…

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…
