First Scan Search for Dark Photon Dark Matter with a Tunable Superconducting Radio-Frequency Cavity
SHANHE Collaboration, Zhenxing Tang, Bo Wang +16
Dark photons have emerged as promising candidates for dark matter, and their search is a top priority in particle physics, astrophysics, and cosmology. We report the first use of a…
Birefringence Tomography for Axion Cloud
Yifan Chen, Chunlong Li, Yosuke Mizuno +5
An axion cloud surrounding a supermassive black hole can be naturally produced through the superradiance process. Its existence can be examined by the axion induced birefringence e…
New test on the Einstein equivalence principle through the photon ring of black holes
Chunlong Li, Hongsheng Zhao, Yi-Fu Cai
Einstein equivalence principle (EEP), as one of the foundations of general relativity, is a fundamental test of gravity theories. In this paper, we propose a new method to test the…
CMB polarization analysis on circular scans
Jia-Rui Li, Chunlong Li, Jie Jiang +4
Most cosmic microwave background experiments observe the sky along circular or near-circular scans on the celestial sphere. For such experiments, we show that simple linear systems…
Testing the equivalence principle via the shadow of black holes
Chunlong Li, Sheng-Feng Yan, Lingqin Xue +5
We study the equivalence principle, regarded as the cornerstone of general relativity, by analyzing the deformation observable of black hole shadows. Such deformation can arise fro…
Implications of the possible 21-cm line excess at cosmic dawn on dynamics of interacting dark energy
Chunlong Li, Xin Ren, Martiros Khurshudyan +1
In this paper we study implications of the possible excess of 21-cm line global signal at the epoch of cosmic dawn on the evolutions of a class of dynamically interacting dark ener…
Searching for the Dark Force with 21-cm Spectrum in Light of EDGES
Chunlong Li, Yi-Fu Cai
The EDGES Collaboration has recently announced the detection of the 21-cm spectrum with an absorption profile centred at megahertz, of which the depth is deeper than that expe…
The effective field theory approach of teleparallel gravity, gravity and beyond
Chunlong Li, Yong Cai, Yi-Fu Cai +1
We develop the effective field theory approach to torsional modified gravities, a formalism that allows for the systematic investigation of the background and perturbation levels s…
gravity after GW170817 and GRB170817A
Yi-Fu Cai, Chunlong Li, Emmanuel N. Saridakis +1
The combined observation of GW170817 and its electromagnetic counterpart GRB170817A reveals that gravitational waves propagate at the speed of light in high precision. We apply the…
