Colossal band renormalization and stoner ferromagnetism induced by electron-antiferromagnetic-magnon coupling
T. L. Yu, R. Peng, 2 M. Xu +15
The interactions between electrons and antiferromagnetic magnons (AFMMs) are important for a large class of correlated materials. For example, they are the most plausible pairing g…
Phonon-enhanced superconductivity at the FeSe/SrTiO3 interface
Q. Song, T. L. Yu, X. Lou +9
The dream of room temperature superconductors has inspired intense research effort to find routes for enhancing the superconducting transition temperature (Tc). Therefore, single-l…
Surface electronic structure and isotropic superconducting gap in (LiFe)OHFeSe
X. H. Niu, R. Peng, H. C. Xu +13
Using angle-resolved photoemission spectroscopy (ARPES), we revealed the surface electronic structure and superconducting gap of (LiFe)OHFeSe, an intercalated FeSe-…
Direct observation of heavy quasiparticles in the Kondo lattice CeIn3
Y. Zhang, W. Feng, X. Lou +15
The electronic structure of the Kondo lattice CeIn3 has been studied by on-resonant angle-resolved photoemission spectroscopy and scanning tunneling microscopy/spectroscopy. A weak…
Distinct Kondo Screening Behaviors in Heavy Fermion Filled Skutterudites with 4f1 and 4f2 Configurations
X. Lou, H. C. Xu, T. L. Yu +9
Filled-skutterudite heavy fermion (HF) compounds host rich ground states depending on the f electron configurations. CeOs4Sb12 (COS) with Ce 4f1, and PrOs4Sb12 (POS) with Pr 4f2 co…
Identification of prototypical Brinkman-Rice Mott physics in a class of iron chalcogenides superconductors
X. H. Niu, S. D. Chen, J. Jiang +17
The 122 series of iron-chalcogenide superconductors, for example KFeSe, only possesses electron Fermi pockets. Their distinctive electronic structure challe…
