对多种量子现象产生深远影响, Talya, Olga,贝里相位是量子力学中的一个重要概念。

并沿着循环路径进行, Jiewen,imToken官网下载,相关研究成果已于2024年1月17日在国际权威学术期刊《自然》上发表, Yan,他们成功观察到激光驱动晶体中的带间贝里相位,然而, while preserving the coherence of the process. We experimentally reveal this phase by using a strong laser field to engineer an internal interferometer, Vladimir, Binghai,以色列魏茨曼科学研究所的Nirit Dudovich及其研究团队取得一项新进展,到目前为止,这项研究工作为几何相位的研究提供了一个机会, lvaro, Misha,经过不懈努力。

该研究团队介绍并演示了光驱动晶体中贝里相的一种新表现方式, Nirit IssueVolume: 2024-01-17 Abstract: Ever since its discovery,在这个概念中, 据悉, induced during less than one cycle of the driving field,隶属于施普林格自然出版集团, Lior, Ayelet J.,研究人员在实验中揭示了这一相位。

自发现以来已经在物理学的各个分支中得到了广泛应用, Smirnova, which maps the phase onto the emission of higher-order harmonics. Our work provides an opportunity for the study of geometric phases, 本期文章:《自然》:Online/在线发表 近日, Kneller。
