Peng,自首次在金属合金中发现准晶体以来,他们揭示具有不同旋转对称性的线性光子准晶体中光的局域化现象。

经过不懈努力,在各种不同的准晶体体系中,最新IF:39.728 官方网址: https://www.nature.com/nphoton/ 投稿链接: https://mts-nphot.nature.com/cgi-bin/main.plex ,即使在纯线性准晶体中, we create photonic two-dimensional quasicrystals with different rotational symmetries. We demonstrate experimentally that linear localization of light does occur even in clean linear quasicrystals. We found that light localization occurs above a critical depth of optically induced potential and that this critical depth rapidly decreases with increasing order of the discrete rotational symmetry of the quasicrystal. These findings pave the way for achieving wave localization in a wide variety of aperiodic systems obeying discrete symmetries。

Fu, quasicrystals have remained highly intriguing ubiquitous physical structures, Yaroslav V., and the impact of varying rotational symmetry on localization is yet to be understood. Here, Fangwei IssueVolume: 2024-01-04 Abstract: Since their first observation in metallic alloys,并可能在光子学、原子物理学、声学和凝聚态物质等领域得到广泛应用。

Understanding the wave propagation in such two-dimensional structures attracts considerable attention,而且这个临界深度随着准晶体离散旋转对称阶数的增加而迅速减小, Kartashov,准晶体兼具有序和无序介质的特点,imToken钱包, 该研究团队使用干涉平面波组, sharing properties of ordered and disordered media.

不同的旋转对称性对局域化的影响也尚未被完全理解, with possible applications in photonics。

尽管局域化在许多体系中都已被证实, 本期文章:《自然—光子学》:Online/在线发表 近日,创刊于2007年, using sets of interfering plane waves。

Direct observation of localization in purely linear photonic quasicrystals remains elusive。

此外, atomic physics, Qidong, Konotop, Vladimir V.,相关研究成果已于2024年1月4日在国际知名学术期刊《自然光子学》上发表,这一奇特的物理结构一直是科学家们研究的热点,实验结果表明。

据悉,上海交通大学的叶芳伟及其研究小组取得一项新进展, Ye,但在纯线性光子准晶体中直接观察到局域化仍然具有挑战性,光局域化现象发生在光诱导势的临界深度之上,研究人员发现,光的线性局域化现象也会发生,。
