The Axion Helical Misalignment Mechanism
Wei Chao, Chang-Jie Dai
Understanding axion production in the early Universe remains a pivotal challenge, given the axion as a compelling cold dark matter candidate. Conventional misalignment scenarios of…
Constraint on ultralight Nelson-Barr dark matter from time-dependent nuclear decay
Chang-Jie Dai, Tong Li
Many experiments have notably reported anomalies in radioactive decay rates with periodic variations and challenged the traditional belief of time-independent decays. This periodic…
Dark Photon Dark Matter in Quantum Electromagnetodynamics and Detection at Haloscope Experiments
Chang-Jie Dai, Tong Li, Rui-Jia Zhang
The ultralight dark photon is one of intriguing dark matter candidates. The interaction between the visible photon and dark photon is introduced by the gauge kinetic mixing between…
Sensitivity of two-mode SRF cavity to generic electromagnetism of sub-eV dark matter
Chang-Jie Dai, Tong Li, Rui-Jia Zhang
The low-mass dark matter (DM) such as axion or wavelike scalar is a plausible DM candidate. Recently, the possible non-standard couplings of low-mass DM has drawn much attention. I…
