Emergence of Quasiparticles in a Doped Mott Insulator
Yao Wang, Yu He, Krzysztof Wohlfeld +9
How a Mott insulator develops into a weakly coupled metal upon doping is a central question to understanding various emergent correlated phenomena. To analyze this evolution and it…
Mode-selective coupling of coherent phonons to the Bi2212 electronic band structure
S. -L. Yang, J. A. Sobota, Y. He +5
Cuprate superconductors host a multitude of low-energy optical phonons. Using time- and angle-resolved photoemission spectroscopy, we study coherent phonons in BiSrCa$_…
The Nematic Energy Scale and the Missing Electron Pocket in FeSe
Ming Yi, Heike Pfau, Yan Zhang +12
Superconductivity emerges in proximity to a nematic phase in most iron-based superconductors. It is therefore important to understand the impact of nematicity on the electronic str…
Fermi surface reconstruction in electron-doped cuprates without antiferromagnetic long-range order
J. -F. He, C. R. Rotundu, M. S. Scheurer +12
Fermi surface (FS) topology is a fundamental property of metals and superconductors. In electron-doped cuprate Nd2-xCexCuO4 (NCCO), an unexpected FS reconstruction has been observe…
Metallic surface states in a correlated d-electron topological Kondo insulator candidate FeSb2
Ke-Jun Xu, Su-Di Chen, Yu He +9
The resistance of a conventional insulator diverges as temperature approaches zero. The peculiar low temperature resistivity saturation in the 4f Kondo insulator (KI) SmB6 has spur…
Rapid change of superconductivity and electron-phonon coupling through 19% doping in Bi2212
Yu He, Makoto Hashimoto, Dongjoon Song +12
Electron-boson coupling plays a key role in superconductivity for many systems. However, in copper-based high-temperature () superconductors, its relation to superconductivity…
