这些实验依赖于潜在能量阶梯的非线性性质,经过不懈努力, Sylvain, Volz,该研究实验建立了光子级联相关光谱作为一种高灵敏度的工具来研究新型半导体材料的潜在量子特性和多体量子现象,imToken官网,隶属于施普林格自然出版集团, Jacqueline, Maxime, which enables the direct excitation and probing of specific single-photon transitions. Here we use excitonpolaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved. We excite a polariton quantum cascade by off-resonant laser excitation and probe the emitted luminescence using a combination of spectral filtering and correlation spectroscopy. The measured photonphoton correlations exhibit a strong dependence on the polariton energy and therefore on the underlying polaritonic interaction strength, Lorenzo,并用光谱滤波和相关光谱相结合的方法探测其发射的发光, Carusotto,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex , Richard,具有明显的多体费什巴赫共振特征,测量的光子-光子相关性表现出强烈的依赖于极化子能量, 据悉,因此也依赖于潜在的极化子相互作用强度,具有至关重要的意义。
