Re-examination of electronic structure of dilute Kondo transition-metal ions substituted into a Heavy Fermion compound
Kou Takubo, Shintaro Suzuki, Kohei Yamamoto +9
Correlations between the localized and conductive spins/charges have been the central issue of various fascinating quantum phenomena found on itinerant electron systems. Here, the…
Ambipolar doping-induced surface in-gap state on Mott-insulating CaRuO
M. Horio, T. Wada, V. Granata +4
We report an x-ray photoemission spectroscopy study of CaRuO surface-dosed with Cs alkali atoms and C molecules. Due to its small ionization energy (large electron a…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
Anatomy of anomalous Hall effect due to magnetic fluctuations
Ola Kenji Forslund, Xiaoxiong Liu, Soohyeon Shin +16
The anomalous Hall {\color{black} e}ffect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Abs…
Inhomogeneous reduction-annealing effects on the electron-doped cuprate superconductor revealed by micro-focused angle-resolved photoemission spectroscopy
M. Miyamoto, M. Horio, K. Moriya +8
The development of the protect-annealing method has extended the superconductivity of the electron-doped cuprate PrLaCeCuO (PLCCO) into lower Ce conce…
