Journal ArticleDOI
Purely Coherent Nonlinear Optical Response in Solution Dispersions of Graphene Sheets
Rui Wu,Yingli Zhang,Shichao Yan,Fei Bian,Wenlong Wang,Xuedong Bai,Xinghua Lu,Jimin Zhao,Enge Wang +8 more
TL;DR: The results suggest that this coherent light scattering is due to a broadband, ultrafast, and remarkably huge third-order optical nonlinearity χ(3), which is a manifestation of the graphene's cone-shaped large-energy-scale band structure.
Journal ArticleDOI
Control of quantum magnets by atomic exchange bias
TL;DR: It is demonstrated that exchange coupling with the magnetic tip of a scanning tunnelling microscope provides continuous tuning of spin state mixing in an individual nanomagnet, demonstrating the feasibility of complete control over individual quantum magnets with atomically localized exchange coupling.
Journal ArticleDOI
Orbital-selective Dirac fermions and extremely flat bands in frustrated kagome-lattice metal CoSn
Zhonghao Liu,Man Li,Man Li,Qi Wang,Guangwei Wang,Chenhaoping Wen,Kun Jiang,Xiangle Lu,Shichao Yan,Yaobo Huang,Dawei Shen,Jiaxin Yin,Ziqiang Wang,Zhiping Yin,Hechang Lei,Shancai Wang +15 more
TL;DR: The observation of a flat band and Dirac bands as ideal features of kagome bands in CoSn, revealing orbital-selective character of the Dirac fermions.
Journal ArticleDOI
Influence of Domain Walls in the Incommensurate Charge Density Wave State of Cu Intercalated 1 T − TiSe 2
TL;DR: Density of states measurements indicate that the domain walls host an extra population of fermions near the Fermi level which may play a role in the emergence of superconductivity in this system.
Journal ArticleDOI
Orbital-selective Dirac fermions and extremely flat bands in frustrated kagome-lattice metal CoSn.
Zhonghao Liu,Man Li,Man Li,Qi Wang,Guangwei Wang,Chenhaoping Wen,Kun Jiang,Xiangle Lu,Shichao Yan,Yaobo Huang,Dawei Shen,Jiaxin Yin,Ziqiang Wang,Zhiping Yin,Hechang Lei,Shancai Wang +15 more
TL;DR: In this article, the authors present close-to-textbook kagome bands with orbital differentiation physics in CoSn, which can be well described by a minimal tight-binding model with single-orbital hopping in Co kagomes.
