Population inversion and Dirac fermion cooling in 3D Dirac semimetal CdAs
Changhua Bao, Qian Li, Sheng Xu +8
Revealing the ultrafast dynamics of three-dimensional (3D) Dirac fermions upon photoexcitation is critical for both fundamental science and device applications. So far, how the coo…
Spatially-resolved electronic structure of stripe domains in IrTe through electronic structure microscopy
Changhua Bao, Hongyun Zhang, Qian Li +11
Phase separation in the nanometer- to micrometer-scale is characteristic for correlated materials, for example, high temperature superconductors, colossal magnetoresistance mangani…
Experimental evidence of plasmarons and effective fine structure constant in electron-doped graphene/h-BN heterostructure
Hongyun Zhang, Shuopei Wang, Eryin Wang +13
Electron-electron interaction is fundamental in condensed matter physics and can lead to composite quasiparticles called plasmarons, which strongly renormalize the dispersion and c…
Coexistence of extended flat band and Kekulé order in Li-intercalated graphene
Changhua Bao, Hongyun Zhang, Xi Wu +6
Doping graphene near the 1/4 filling to shift the extended flat band and van Hove singularity below E has been highly desirable. Here we report the experimental observation of…
Experimental evidence of chiral symmetry breaking in Kekulé-ordered graphene
Changhua Bao, Hongyun Zhang, Teng Zhang +13
The low-energy excitations of graphene are relativistic massless Dirac fermions with opposite chiralities at valleys K and K'. Breaking the chiral symmetry could lead to gap openin…
Self-energy dynamics and mode-specific phonon threshold effect in a Kekulé-ordered graphene
Hongyun Zhang, Changhua Bao, Michael Schüler +7
Electron-phonon interaction and related self-energy are fundamental to both the equilibrium properties and non-equilibrium relaxation dynamics of solids. Although electron-phonon i…
