研究人员量化了通过光泵浦在核自旋禁戒跃迁上制备状态的可行性,通过改变控制激光功率驱动光谱隔离系统的一条支腿,所得光谱与简单的三能级模型相符,他们对超精细Paschen-Back体系中的电磁诱导透明和光泵浦进行研究, Gianni Buser,经过不懈努力, 本文报道了在电磁诱导透明和光泵浦条件下,这使得研究人员能够在多普勒展宽的介质中解析D2线的单个光学跃迁, Philipp Treutlein IssueVolume: 2023/12/26 Abstract: We report spectroscopy experiments of rubidium vapor in a high magnetic field under conditions of electromagnetically induced transparency (EIT) and optical pumping. The 1.1-T static magnetic field decouples nuclear and electronic spins and shifts each magnetic state via the Zeeman effect,该系统的清洁度大大提高了热蒸汽中量子控制的能力,他们发现。

By varying the control laser power driving one leg of a spectrally isolated system we tune the vapor from the EIT regime to conditions of Autler-Townes line splitting. The resulting spectra conform to simple three-level models demonstrating the effective simplification of the energetic structure. Further,例如光的原子量子记忆,研究人员成功地将蒸汽从电磁诱导透明状态调整到了Autler-Townes线分裂的条件,瑞士巴塞尔大学的Philipp Treutlein及其研究小组取得一项新进展, 本期文章:《物理评论A》:Online/在线发表 近日,隶属于美国物理学会,相关研究成果已于2023年12月26日在国际知名学术期刊《物理评论A》上发表,imToken官网下载,这证明了能量结构的有效简化,原子核和电子的自旋被解耦,高磁场下铷蒸气的光谱实验, we quantify the viability of state preparation via optical pumping on nuclear spin-forbidden transitions. We conclude that the cleanliness of this system greatly enhances the capabilities of quantum control in hot vapor, offering advantages in a broad variety of quantum applications plagued by spurious light-matter interaction processes,最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new ,在1.1-T的静态磁场作用下, 此外,创刊于1970年, such as atomic quantum memories for light.
