论文摘要
在存在外部磁场的情况下,轴和光子混合物。特别是,纵向等离子体的分散关系始终越过轴轴的分散关系(对于小轴支质量),从而导致谐振转化。使用热场理论,我们简洁地得出了轴突排放率,将其应用于天体物理和实验室场景。对于太阳,根据磁场曲线的不同,等离子轴转换可以在低能($ \ lyssim 200 \,$ eV)下占主导地位。这两者都为将来的射镜提供了一个新的斧头源,并且在发现的情况下,它将探测太阳的磁场结构。在白矮人(WDS)的情况下,等离子体轴转换提供了轴轴的纯光子耦合探针,这可能对低质量WDS有显着贡献。最后,我们重新培养并确认最近提出的血浆卤素化的轴突吸收率。
In the presence of an external magnetic field the axion and the photon mix. In particular, the dispersion relation of a longitudinal plasmon always crosses the dispersion relation of the axion (for small axion masses), thus leading to a resonant conversion. Using thermal field theory we concisely derive the axion emission rate, applying it to astrophysical and laboratory scenarios. For the Sun, depending on the magnetic field profile plasmon-axion conversion can dominate over Primakoff production at low energies ($\lesssim 200\,$eV). This both provides a new axion source for future helioscopes and, in the event of discovery, would probe the magnetic field structure of the Sun. In the case of white dwarfs (WDs), plasmon-axion conversion provides a pure photon coupling probe of the axion, which may contribute significantly for low-mass WDs. Finally we rederive and confirm the axion absorption rate of the recently proposed plasma haloscopes.
