Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
Superconductivity in an electron band just above the Fermi level: possible route to BCS-BEC superconductivity
Kozo Okazaki, Yoshiaki Ito, Yuichi Ota +10
Conventional superconductivity follows Bardeen-Cooper-Schrieffer(BCS) theory of electrons-pairing in momentum-space, while superfluidity is the Bose-Einstein condensation(BEC) of a…
Influence of anti-site disorder and electron-electron correlations on the electronic structure of CeMnNi
Pampa Sadhukhan, Sunil Wilfred D'Souza, Vipin Kumar Singh +7
CeMnNi exhibits an unusually large spin polarization, but its origin has baffled researchers for more than a decade. We use bulk sensitive hard x-ray photoelectron spectroscopy…
Electronic Structure of Strained Manganite Thin Films with Room Temperature Ferromagnetism Investigated by Hard X-ray Photoemission Spectroscopy
Hidekazu Tanaka, Yasutaka Takata, Koji Horiba +11
We report the bulk sensitive Hard X-ray (hv=5.95keV) core level photoemission spectroscopy to investigate the intrinsic electronic structure of strained (La0.85Ba0.15)MnO3 thin fil…
