Axion production in unstable magnetized plasmas
Axions, the hypothetical particles restoring the charge-parity symmetry in the strong sector of the Standard Model and one of the most prone candidates for dark matter, are well known to interact with plasmas. In a recent publication [Phys. Rev. Lett. 120, 181803 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.181803], we show that if the plasma dynamically responds to the presence of axions, then a new quasiparticle (the axion-plasmon polariton) can be formed, being at the basis of a new generation of plasma-based detection techniques. In this work, we exploit the axion-plasmon hybridization to actively produce axions in streaming magnetized plasmas. The produced axions can then be detected by reconversion into photons in a scheme that is similar to the light-shining-through-a-wall experiments.
