Strong- to weak-coupling superconductivity in high- bismuthates: revisiting the phase diagram via SR
T. Shang, D. J. Gawryluk, M. Naamneh +6
Several decades after the discovery of superconductivity in bismuthates, the strength of their electron-phonon coupling and its evolution with doping remain puzzling. To clarify th…
Two-dimensional type-II Dirac fermions in layered oxides
M. Horio, C. E. Matt, K. Kramer +11
Relativistic massless Dirac fermions can be probed with high-energy physics experiments, but appear also as low-energy quasi-particle excitations in electronic band structures. In…
Three- to Two-Dimensional Transition of the Electronic Structure in CaFe2As2 - parent compound for an iron arsenic high temperature superconductor
Chang Liu, Takeshi Kondo, Ni Ni +9
We use angle-resolved photoemission spectroscopy (ARPES) to study the electronic properties of CaFe2As2 - parent compound of a pnictide superconductor. We find that the structural…
Observation of well-defined quasi-particle over a wide energy range in quasi-2D system
L. -L. Jia, Z. -H. Liu, Y. -P. Cai +12
We report the observation by angle-resolved photoemission spectroscopy measurements of a highly anisotropic Dirac-cone structure in high quality SrMnBi2 crystals. We reveal a well-…
Tuning electronic correlations in transition metal pnictides: chemistry beyond the valence count
E. Razzoli, C. E. Matt, M. Kobayashi +14
The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the researc…
Unconventional transverse transport above and below the magnetic transition temperature in Weyl semimetal EuCdAs
Y. Xu, L. Das, J. Z. Ma +10
As exemplified by the growing interest in the quantum anomalous Hall effect, the research on topology as an organizing principle of quantum matter is greatly enriched from the inte…
