Multiband topological group-velocity control from slow light to light stopping
Junhao Yang, Jiarui Wang, Jingyu Liu +2
We introduce next-nearest-neighbor (NNN) couplings into a Harper--Hofstadter photonic lattice to establish a long-range topological photonic platform for group-velocity engineering…
Feedback-Controlled Magnon-Atom Entanglement and Photon Statistics
Yiping Lu, Yulong Hu, Zhuzheng Han +1
Quantum systems face inherent challenges in achieving precise control, and solving the Schrödinger equation is often intractable for complex hybrid platforms. Here, for the first…
Tunable Rotation-Associated Slow-to-Fast Light Conversion via Optomagnonic Coupling
Jingyu Liu, Shirong Lin
Cavity optomechanics has enabled slow-to-fast light conversion, but traditional optomechanic systems suffer from limited tunability due to fixed mechanical frequencies. To address…
Magnetic Skyrmion Encoding by Structured Light
Zhang Qifan, Yu Wangke, Nie Zhongquan +2
Structured light fields, featuring unique topological properties and high tunability, have opened new frontiers in light-matter interactions with magnetic systems. However, the ult…
Twisted bi-layer magnetic photonic crystals
You-Ming Liu, Shi-Kai Lin, Pei-Shi Li +2
In photonics, twisted bi-layer systems have demonstrated unprecedented control over light-matter interactions, primarily through the modulation of photonic band structures and the…
Coupling phase enabled level transitions in pseudo-Hermitian magnon-polariton systems
Huang Xin, Liu Jingyu, Lin Shirong
While cavity-magnon hybridization offers intriguing physics, its practical implementation is hindered by intrinsic damping in both cavity and magnon modes, leading to short coheren…
