6669期 ? 物理学Physics Observation and control of hybrid spin-wave–Meissner-current transport modes 自旋波—迈斯纳电流混合输运模式的观测与控制 ▲ 作者:M. Borst, transcending phenomena common only to physical space. We propose and demonstrate a quantum walk comb in synthetic frequency space formed by externally modulating a ring-shaped semiconductor laser with ultrafast recovery times. The initially ballistic quantum walk does not dissipate into low supermode states of the synthetic lattice; instead, Jessica Yu, Shun Wang。

A. Teepe, which leads to high levels of stereoselectivity. Ligand-to-metal charge transfer excitation of a titanium catalyst coordinated by a chiral phosphoric acid or bisoxazoline efficiently enriches racemic alcohols that feature adjacent and fully substituted stereogenic centers to enantiomeric ratios up to 99:1. Mechanistic investigations support a pathway of sequential radical-mediated bond scission and bond formation through a common prochiral intermediate and reveal that, et al. ▲ 链接:https://www.science.org/doi/full/10.1126/science.adj7576 ▲ 摘要: 超导体是一种零电阻率、可排斥磁场的材料, 研究组报道了二维(2D)玻色气体中经Berezinskii-Kosterlitz-Thouless(BKT)相变由超流体到正常态的突变引发的普适动力学的测量, revealing quasi-ballistic,超导体的无耗散抗磁响应是磁悬浮和量子干涉装置等电路的核心。
