Recovering lossless propagation of polaritons with synthesized complex frequency excitation
Fuxin Guan, Xiangdong Guo, Shu Zhang +8
Surface plasmon polaritons and phonon polaritons offer a means of surpassing the diffraction limit of conventional optics and facilitate efficient energy storage, local field enhan…
Synthesized complex-frequency excitation for ultrasensitive molecular sensing
Kebo Zeng, Chenchen Wu, Xiangdong Guo +7
Detecting trace molecules remains a significant challenge. Surface-enhanced infrared absorption (SEIRA) based on plasmonic nanostructures, particularly graphene, has emerged as a p…
Electron-infrared phonon coupling in ABC trilayer graphene
Xiaozhou Zan, Xiangdong Guo, Aolin Deng +18
Stacking order plays a crucial role in determining the crystal symmetry and has significant impacts on electronic, optical, magnetic, and topological properties. Electron-phonon co…
Approaching the Purcell factor limit with whispering-gallery hyperbolic phonon polaritons in hBN nanotubes
Xiangdong Guo, Ning Li, Xiaoxia Yang +9
Enhanced light-matter interaction at the nanoscale is pivotal in the foundation of nonlinear optics, quantum optics, and nanophotonics, which are essential for a vast range of appl…
THz Near-Field Imaging of Extreme Subwavelength Metal Structures
Xinzhong Chen, Xiao Liu, Xiangdong Guo +15
Modern scattering-type scanning near-field optical microscopy (s-SNOM) has become an indispensable tool in material research. However, as the s-SNOM technique marches into the far-…
