The electroweak magnetic monopole in the presence of KSVZ axion
Tong Li, Rui-Jia Zhang
The Witten effect implies the dynamics of axion and magnetic monopole. The Cho-Maison monopole is a realistic electroweak monopole arisen in the Weinberg-Salam theory. This monopol…
Constraints on light dark matter from primordial black hole evaporation at dark matter direct detection experiments
Tong Zhu, Cheng-Rui Jiang, Tong Li +1
Primordial black holes (PBHs) are able to produce light dark matter (DM) particles via Hawking radiation, and yield a flux of boosted DM that can be probed at underground DM direct…
Solutions to axion electrodynamics with electric-magnetic duality in supersymmetric Seiberg-Witten theory
Tong Li, Rui-Jia Zhang
Axion and magnetic monopole are among the most fascinating candidates for physics beyond the Standard Model. The potential connection between axion and magnetic monopole stems from…
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…
Probing light axion-like particle via primordial black hole evaporation with gamma-ray observations
Tong Li, Rui-Jia Zhang
The axion-like particle (ALP) and primordial black hole (PBH) are two representative dark matter (DM) candidates as light bosonic DM and macroscopic objects, respectively. In this…
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…
