A common perception is that laboratory tests of fundamental physics necessarily require large particle colliders. However, thanks to the development of ultra high-intensity optical lasers and 4th generation light sources, new approaches are now possible that exploit the simultaneous interactions of multiple photons with matter and vacua via quantum field fluctuations. In this proposal, we will employ these high-field non-perturbative quantum optics processes to search for new fundamental particles. Since accelerator-based searches have not yet found new physics at high energies, ultra high-intensity optical lasers and 4th generation light sources offer a novel complementary approach for searches at optical and X-ray energies. This proposal addresses an important question in fundamental physics by developing a laboratory search for new particles beyond the Standard Model called axions. Our work will be able to probe axion masses bigger than a few eV up to a keV - a region that is currently inaccessible to laboratory searches. In the eV-keV mass range. the searches proposed here are the only model-independent ones, meaning that the experiments have full control over both the production and reconversion of axions within the same apparatus - without the need to assume that axions are produced by astrophysical objects (such as the Sun) or constitute a large fraction of the dark matter.

一个普遍的看法是，基本物理学的实验室测试必定需要大的粒子壁。但是，由于超高强度光激光器和第四代光源的发展，现在有可能通过量子场波动来利用多个光子与物质和真空的同时相互作用。在此提案中，我们将采用这些高场非扰动量子光学器件来搜索新的基本粒子。由于基于加速器的搜索尚未在高能量上找到新的物理，因此超高强度的光学激光器和第四代光源为光学和X射线能量的搜索提供了一种新颖的补充方法。该提案通过开发出对标准模型的新粒子的实验室搜索来解决基本物理学的一个重要问题。我们的工作将能够探测大于少数电动汽车到kev的轴质量，直到kev是一个目前无法访问实验室搜索的区域。在EV-KEV质量范围内。这里提出的搜索是唯一与模型无关的搜索，这意味着实验对同一设备内轴的产生和重新进行了完全控制 - 而无需假设轴是由天体物理物体（例如太阳）产生的，或者构成了暗物质的大部分。
