Revisiting the Axial Anomaly and Chiral Magnetic Effect in Dense Matter, with Applications to Axion Dark Matter
Deog Ki Hong
We explicitly compute the axial anomaly in dense matter and show that its form remains unchanged from that in vacuum, even in the massless limit. This result follows from a subtle…

Probing the axion-electron coupling at cavity experiments
Deog Ki Hong, Sang Hui Im, Jinsu Kim +2
Axion dark matter induces electromagnetic radiation in conductors through nearly perpetual oscillations of electrons, driven by axion-electron interactions through the so-called ch…

Q-ball collisions and their Gravitational Waves
Deog Ki Hong, Stephen J. Lonsdale
Sydney Coleman's Q-ball remains a compelling instance of localised object formation within classical field theory, independently of the quantum evolution. The theoretical possibili…
