Measuring exciton polaritons in lithium triborate (LBO) by x-ray parametric d...

In previous experiments on x-ray parametric down-conversion (XPDC), we successfully resolved the splitting into highly asymmetric (i.e., x-ray and EUV) photon pairs. We observed...在过往针对X射线参量下转换（X-ray parametric down-conversion, XPDC）的实验中，我们成功分辨出了分裂生成的高度非对称光子对——即X射线与极紫外（Extreme Ultraviolet, EUV）光子对。我们观测到……
