Bulk superconductivity at 84 K in the strongly overdoped regime of cuprates
A. Gauzzi, Y. Klein, M. Nisula +8
By means of magnetization, specific heat and muon-spin relaxation measurements, we investigate high-pressure oxidized \mohpo, in which overdoping is achieved up to ho…
Two-Dimensional Far-Field Correlations of X-ray Photon Pairs
E. Strizhevsky, Y. Klein, R. Hartmann +9
We directly observe far-field correlations of x-ray photon pairs generated by spontaneous parametric down-conversion (SPDC). Using an energy-resolved, two-dimensional photon counti…
Dichroism in time-resolved ARPES and valence band orbital nature in BaNiS2
J. Zhang, Z. Chen, J. Caillaux +7
Time-resolved ARPES gives access to the band structure and ultrafast dynamics of excited electronic states in solids. The orbital character of the bands close to the Fermi level is…
Electron localization and possible phase separation in the absence of a charge density wave in single-phase 1T-VS
A. Gauzzi, A. Sellam, G. Rousse +12
We report on a systematic study of the structural, magnetic and transport properties of high-purity 1T-VS powder samples prepared under high pressure. The results differ notabl…
25-Fold Resolution Enhancement of X-ray Microscopy Using Multipixel Ghost Imaging
O. Sefi, A. Ben Yehuda, Y. Klein +4
Hard x-ray imaging is indispensable across diverse fields owing to its high penetrability. However, the resolution of traditional x-ray imaging modalities, such as computed tomogra…
Ferroelectricity in the 1 C cm range induced by canted antiferromagnetism in (LaMn)MnO
A. Gauzzi, F. Milton, V. Pascotto Gastaldo +8
Pyroelectric current and magnetoelectric coupling measurements on polycrystalline samples of the quadruple perovskite (LaMn)MnO give evidence of ferroelectricity…
