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…
Dimensionality-Dependent Exciton Dispersion in a Single-Band Mott Insulator
Zhibin Su, Junjian Mi, Shaohua Yan +9
Excitonic band structure is critical for investigating exciton dynamics. Theoretically, quantum effects from exchange scattering between electron-hole pairs significantly modulate…
From Ferromagnet to Antiferromagnet: Dimensional Crossover in (111) SrRuO3 Ultrathin Films
Zhaoqing Ding, Xuejiao Chen, Lei Liao +11
SrRuO3 is a canonical itinerant ferromagnet, yet its properties in the extreme two-dimensional limit on a (111) crystal plane remain largely unexplored. Here, we demonstrate a comp…
Tuning the Magnetism in Ultrathin CrxTey Films by Lattice Dimensionality
Guangyao Miao, Minghui Gu, Nuoyu Su +7
Two-dimensional (2D) magnetic transition metal compounds with atomic thickness exhibit intriguing physics in fundamental research and great potential for device applications. Under…
Observation of the Breakdown of Optical Phonon Splitting in a Two-dimensional Polar Monolayer
Jiade Li, Li Wang, Zhiyu Tao +6
Phonon splitting of the longitudinal optical and transverse optical modes (LO-TO splitting), a ubiquitous phenomenon in three-dimensional (3D) polar materials, is essential for the…
Geometric Effect of High-Resolution Electron Energy Loss Spectroscopy on the Identification of Plasmons: An Example of Graphene
Jiade Li, Zijian Lin, Guangyao Miao +7
High-resolution electron energy loss spectroscopy (HREELS) is one of the most powerful methods to detect the dispersion of plasmons. However, we find that in the HREELS measurement…
