论文摘要
Bose-Einstein凝结是一种以材料颗粒为冷原子气体而闻名的效果，近年来也观察到微观光学圆柱的光子的光子。 Here, we report absorption and emission spectroscopic measurements on the lowest electronic transition ($5\text{p}^6 \rightarrow 5\text{p}^5 6\text{s}$) of xenon, motivated by the search for a thermalization medium for photon Bose-Einstein condensation in the vacuum-ultraviolet spectral regime.在临界点附近的条件下，我们在135 nm至190 nm波长状态下记录了压力宽的氙光谱。经过探索的压力和温度范围包括室温下临界压力和超临界氙气的高压气态氙气，以及靠近临界压力靠近沸点的液体氙气。
Bose-Einstein condensation, an effect long known for material particles as cold atomic gases, has in recent years also been observed for photons in microscopic optical cavitites. Here, we report absorption and emission spectroscopic measurements on the lowest electronic transition ($5\text{p}^6 \rightarrow 5\text{p}^5 6\text{s}$) of xenon, motivated by the search for a thermalization medium for photon Bose-Einstein condensation in the vacuum-ultraviolet spectral regime. We have recorded pressure-broadened xenon spectra in the 135 nm to 190 nm wavelength regime at conditions near the critical point. The explored pressure and temperature range includes high pressure gaseous xenon below the critical pressure and supercritical xenon at room temperature, as well as liquid xenon close to the boiling point near the critical pressure.
