Dynamic Lasing of Axion Clusters
Liang Chen, Thomas W. Kephart
We examine high-density axion clusters under gravitational compression. These are transient events in which the majority of axions are rapidly converted into photons, with some con…

Measuring Coherent Radio and Microwave Photons from the Solar Corona
Liang Chen, Zizang Qiu, Thomas W. Kephart +1
The rates of production of radio/microwave N-identical photons states |N> from stimulated emission in the solar atmosphere are estimated. Effects of various decohering factors are…

Effects of stimulated emission and superradiant growth of non-spherical axion cluster
Liang Chen, Da Huang, Chao-Qiang Geng
We explore the stimulated emission of photons in non-spherical axion clusters with or without the axion source from the superradiance of a rotating black hole (BH). In particular,…
