Low-velocity-favored transition radiation
Jialin Chen, Ruoxi Chen, Zheng Gong +8
When a charged particle penetrates through an optical interface, photon emissions emerge - a phenomenon known as transition radiation. Being paramount to fundamental physics, trans…
Bulk-plasmon-mediated free-electron radiation beyond the conventional formation time
Fuyang Tay, Xiao Lin, Xihang Shi +3
Free-electron radiation is a fundamental photon emission process that is induced by fast-moving electrons interacting with optical media. Historically, it has been understood that,…
Observation of Topological Corner State Arrays in Photonic Quasicrystals
Aoqian Shi, Yiwei Peng, Jiapei Jiang +8
Recently, the studies of topological corner states (TCSs) are extended from crystals to quasicrystals, which are referred to as higher-order topological quasicrystalline insulators…
Demonstration of broadband topological slow light
Fujia Chen, Haoran Xue, Yuang Pan +12
Slow-light devices are able to significantly enhance light-matter interaction due to the reduced group velocity of light, but a very low group velocity is usually achieved in a nar…
Observation of Dirac hierarchy in three-dimensional acoustic topological insulators
Linyun Yang, Yin Wang, Yan Meng +12
Dirac cones (DCs) play a pivotal role in various unique phenomena ranging from massless electrons in graphene to robust surface states in topological insulators (TIs). Recent studi…
Observation of 2D Cherenkov radiation
Yuval Adiv, Hao Hu, Shai Tsesses +8
For over 80 years of research, the conventional description of free-electron radiation phenomena, such as Cherenkov radiation, has remained unchanged: classical three-dimensional e…
Wide-angle giant photonic spin Hall effect
Zhihao Chen, Yu Chen, Yaodong Wu +5
Photonic spin Hall effect is a manifestation of spin-orbit interaction of light and can be measured by a transverse shift λof photons with opposite spins. The precise measurement o…
Generation of Accelerating Waves in Smith-Purcell Radiation
Liqiao Jing, Dashuang Liao, Jie Tao +2
Metasurface has recently emerged as a powerful platform to engineer wave packets of free electron radiation at the mesoscale. Here, we propose that accelerating waves can be genera…
