Axions\, hypothetic al particles proposed as an elegant solution to the “strong CP problem ” in the Standard Model\, have gained attention as promising dark matter candidates. Consequently\, there has been strong interest in understandin g their interactions with matter and light under specific conditions.

This work investigates the behaviour of axions in spin-1/2 quantum p lasmas\, with a particular focus on high-density\, low-temperature regimes where spin effects and axion-electron interactions could reveal new dynam ics. Using techniques from quantum field theory and plasma physics\, this research develops a new theory of Axion-Quantum Electrodynamics\, capable of describing axion dynamics in spin-1/2 quantum plasmas.

This s tudy examines the hybridization of bosonic modes present in this environme nt (axions\, plasmons\, and magnons) and explores their effects on the pro pagation of electrostatic and electromagnetic waves by determining their n ew dispersion relation. These findings not only increase our understanding of axion interactions in quantum plasmas\, but also aim to inspire new ax ion detection methods in solid-state and ultra-cold plasma environments\, potentially creating new experimental approaches in axion physics.
