Plasmon Collapse in a Directional Strange Metal
Jiade Li, Peiyi He, Deng Hu +7
Strange metals are widespread in strongly correlated quantum matter and closely intertwined with high-temperature superconductivity and quantum criticality, yet their microscopic c…
Direct Measurement of Exciton Dispersion in the Long-Wavelength Limit
Peiyi He, Jiade Li, Jiakai Wang +15
Exciton dispersion, which governs the propagation, scattering and radiative decay of electron-hole pairs, is essential to optoelectronics and quantum materials. In two-dimensional…
Direct observation of anisotropic exciton dispersion in the 2D semiconductor CrSBr
Yiwen Song, Peiyi He, Weizhe Zhang +7
We report momentum-resolved measurements of exciton dispersion in multilayer CrSBr using defocus-engineered electron energy-loss spectroscopy, supported by first-principles calcula…
Strongly confined Mid-infrared to Terahertz Phonon Polaritons in Ultra-thin SrTiO3
Peiyi He, Jiade Li, Cong Li +7
Phonon polaritons (PhPs) enable subwavelength light control for infrared sensing, imaging, and optoelectronics, but conventional polar materials have narrow Reststrahlen bands, lim…
