论文摘要
我们提出了一种新的实验技术，以在宽轴质量范围内具有良好的实验灵敏度生成和检测实验室中的轴。该方案依赖于使用基于激光的四波混合，这是由假设轴是介导的。强烈的泵和stoke激光梁局限于波导（即，例如光纤），具有适当选择的频率，会共同互动地驱动轴突产生。在这样的几何形状下，我们预测了引导轴向波的存在，我们称之为“轴突”。这些是轴klein-gordon场方程的溶液，在空间上以驱动泵和stokes激光束的轮廓为指导。然后，这些引导的轴测子可以将其搭配到附近的纤维上，并与另一激光混合，从而影响探针激光束的传播。该方案的一个关键优势是，可以通过改变泵的频率和stokes激光束来扫描假设轴的质量范围。我们预测，使用合理的参数，该技术将能够检测质量范围内的轴$ 10^{ - 6} $ ev $ <m <m <m <$ 10^{ - 2} $ eV，其敏感性在$ 10^{-12} $ GEV $ gev $^{ - 1} $中的敏感性，用于Axion-photon photon photon photon coupling Constant。
We propose a new experimental technique to generate and detect axions in the lab with a good experimental sensitivity over a broad axion mass range. The scheme relies on using laser-based four-wave mixing, which is mediated by the hypothetical axion field. Intense pump and Stokes laser beams that are confined to a waveguide (i.e., for example, an optical fiber) with appropriately chosen frequencies resonantly drive axion generation. Under such a geometry, we predict the existence of guided axion waves, which we refer to as "axitons". These are solutions of the axion Klein-Gordon field equation that are spatially guided by the profiles of the driving pump and Stokes laser beams. These guided axitons can then couple to a nearby fiber and mix with another laser, affecting the propagation of a probe laser beam. A key advantage of the scheme is that the mass range of the hypothetical axion can be scanned by varying the frequencies of the pump and the Stokes laser beams. We predict that, using reasonable parameters, the technique will be able to detect axions in the mass range $10^{-6} $eV $< m<$ $10^{-2} $eV with a sensitivity at the level of $10^{-12}$ GeV$^{-1}$ for the axion-photon coupling constant.
