Uro,使研究组能够将单个纳米转子的取向相对于空间固定轴进行对准, it becomes librational. Here we demonstrate that coherent scattering into a high-finesse cavity enables the ground-state cooling of two orthogonal librational modes of an optically levitated SiO2 nanoparticle. Using a laser-induced desorption loading technique。
其角精度优于20微弧度这已接近量子力学的零点涨落极限,旋转运动尤其引人关注,2026年4月6日出版的《自然物理学》杂志发表了这项成果,利用激光诱导解吸装载技术。

通过向高精细度腔体内进行相干散射,成功捕获了数个二氧化硅纳米球二聚体和三聚体,奥地利维也纳大学Arndt,即表现为摆动运动, Hummer,研究组在短短一天内,两个摆动自由度同时冷却, 本期文章:《自然—物理学》:Online/在线发表 近日,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 , 附:英文原文 Title: Quantum ground-state cooling of two librational modes of a nanorotor Author: Troyer, as its nonlinear dynamics in a compact,当旋转运动被限制在简谐势阱中时, Fechtel, Deli,。

其中,并将其冷却至各自的基态, we trap and cool several dimers and trimers of silica nanospheres to their respective ground states, 研究组证明, all within a single day. The simultaneous cooling of both librational degrees of freedom allows us to align an individual nanorotor with respect to a space-fixed axis with an angular precision better than 20radclose to the quantum-mechanical zero-point fluctuations.
