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…
Enhanced Superconductivity and Mixed-dimensional Behaviour in Infinite-layer Samarium Nickelate Thin Films
Mingwei Yang, Heng Wang, Jiayin Tang +24
Rare-earth infinite-layer nickelates represent an emerging class of unconventional superconductors, with materials synthesis largely limited to early lanthanide compounds. Here, we…
Rotational symmetry breaking in superconducting nickelate Nd0.8Sr0.2NiO2 films
Haoran Ji, Yanan Li, Yi Liu +7
The infinite-layer nickelates, isostructural to the high-Tc superconductor cuprates, have risen as a promising platform to host unconventional superconductivity and stimulated grow…
