轴子-光子混合光的圆偏振

On the circular polarisation of light from axion-photon mixing

A. Payez, J. R. Cudell, D. Hutsemékers

摘要:

通过对来自类星体的可见光的线偏振测量结果的分析,已经报道了类星体偏振矢量在天空某些区域存在大尺度相干取向。在这里,我们表明,这可以解释为混合的入射光子与近无质量的赝标量(类轴子)粒子在河外磁场。我们提出了一种新的处理波包,并讨论其影响的圆偏振。

英文摘要:

From the analysis of measurements of the linear polarisation of visible light coming from quasars, the existence of large-scale coherent orientations of quasar polarisation vectors in some regions of the sky has been reported. Here, we show that this can be explained by the mixing of the incoming photons with nearly massless pseudoscalar (axion-like) particles in extragalactic magnetic fields. We present a new treatment in terms of wave packets and discuss its implications for the circular polarisation.
