Data underlying the publication: Modified Bose-Einstein condensation in an optical quantum gas

Our work investigates the Bose-Einstein condensation of photons in an intra-cavity Mach-Zehnder interferometer with controlled dissipation and feedback. The switching behaviour of the interferometer is analysed in order to reveal the physical mechanisms that control the formation of a Bose-Einstein condensate. We show that by adjusting their frequency, Bose-Einstein condensates naturally seek to minimise particle loss and destructive interference in their environment. The provided dataset contains the experimental data used to generate the figures in M. Vretenar, C. Toebes, J. Klaers, “Modified Bose-Einstein condensation in an optical quantum gas”, arXiv:2105.10708 [cond-mat.quant-gas]. The data consists of grayscale tiff images that describe the photon density in the plane of the microcavity used in this experiment. Furthermore, we provide json files that give integrated intensities derived from these images. Further information can be found in the file README.txt provided with the data set and in the above mentioned publication.<br><br>

本研究聚焦于搭载可控耗散与反馈系统的腔内马赫-曾德尔干涉仪（Mach-Zehnder interferometer）中的光子玻色-爱因斯坦凝聚（Bose-Einstein condensation）。通过分析该干涉仪的开关特性，我们揭示了调控玻色-爱因斯坦凝聚形成的物理机制。研究表明，玻色-爱因斯坦凝聚体可通过调节自身频率，自发降低粒子损耗并抑制环境中的相消干涉。

本数据集包含用于生成M. Vretenar、C. Toebes、J. Klaers发表于预印本平台arXiv:2105.10708 [cond-mat.quant-gas]的论文"Modified Bose-Einstein condensation in an optical quantum gas"中插图的实验数据。该数据集由灰度TIFF（Tagged Image File Format）图像构成，用于表征本实验所用微腔平面内的光子密度分布。此外，数据集还附带从上述图像中提取得到的积分强度数据JSON文件。
