评“多铁性中的轴-物质耦合”

Comment on "Axion-matter coupling in multiferroics"

Alexander Balatsky, Benjo Fraser

摘要:

以前的出版物[H。S. Roising等人,Phys. Rev. Research 3,033236(2021)]指出了多铁性中暗物质轴子和铁性序之间的耦合。在这篇评论中,我们认为,使用这种耦合的暗物质传感可能是不可行的,我们考虑的材料类,与当今的技术和水平的材料合成。建议的效果(QCD轴子)是小的,是压倒性的热噪声。这一发现意味着,可能的材料提出的检测方案将需要找到显着较低的磁有序温度。

英文摘要:

A previous publication [H. S. Roising et al., Phys. Rev. Research 3, 033236 (2021)] involving the current authors pointed out a coupling between dark matter axions and ferroic orders in multiferroics. In this comment we argue that using this coupling for dark matter sensing is likely not feasible for the material class we considered, with present-day technologies and level of materials synthesis. The proposed effect (for QCD axions) is small and is overwhelmed by thermal noise. This finding means that likely materials for the proposed detection scheme would need to be found with significantly lower magnetic ordering temperatures.
