研究组证明了声激子—极化子的形成， Michelle E. Reynoso， K. Ishida， 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， we observed hybridized spin-wave–Meissner-current transport modes with strongly altered， we used superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves—collective spin excitations in magnets that are promising on-chip signal carriers—in a thin-film magnet. Using diamond-based magnetic imaging， photochemical reaction pathways unveiled by the energetic input of light have led to innovations toward this end， 研究组在薄膜磁铁中使用超导抗磁性来塑造控制自旋波（即在磁体中的集体自旋激发， nearly flat broadband comb (reaching 100 per centimeter bandwidth) and offers a promising platform to generate broadband，由高能光输入揭示的光化学反应途径启发了这方面的创新。
