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…
Ultrafast time- and angle-resolved photoemission spectroscopy with widely tunable probe photon energy of 5.3-7.0 eV for investigating dynamics of three-dimensional materials
Changhua Bao, Haoyuan Zhong, Shaohua Zhou +3
Time- and angle-resolved photoemission spectroscopy (TrARPES) is a powerful technique for capturing the ultrafast dynamics of charge carriers and revealing photo-induced phase tran…
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…
Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
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…
