利用诱导电子自旋进动探测轴子

Detecting axions via induced electron spin precession

Stephon Alexander, Robert Sims

摘要:

我们提出了一个新的窗口来检测类轴子粒子(ALP)的暗物质从带电费米子,如电子和夸克。我们特别考虑了轴子和电子之间的直接相互作用,发现非相对论量子动力学诱导自旋进动由于轴子和增强的应用程序的外部电场。这种旋进产生了磁通量的变化,在某些情况下,这种变化可以产生SQUID磁强计的可检测信号。

英文摘要:

We propose a new window to detect axion-like particle (ALP) dark matter from electrically charged fermions, such as electrons and quarks. We specifically consider a direct interaction between the axion and the electron and find that the non-relativistic quantum dynamics induces a spin precession due to the axion and is enhanced by the application of an external electric field. This precession gives a change in magnetic flux which under certain circumstances can yield a detectable signal for SQUID magnetometers.
