Electronic Structure and Electron Correlation in LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x
Walid Malaeb, Teppei Yoshida, Takashi Kataoka +10
Photoemission spectroscopy is used to investigate the electronic structure of the newly discovered iron-based superconductors LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x. Line shapes of t…
Band-selective Plasmonic Polaron in Thermoelectric Semimetal TaPdSe with ultra-high power factor
Daiki Ootsuki, Akitoshi Nakano, Urara Maruoka +6
We report the electronic structure of the thermoelectric semimetal TaPdSe with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved…
Proximity-Induced Nodal Metal in an Extremely Underdoped CuO Plane in Triple-Layer Cuprates
Shin-ichiro Ideta, Shintaro Adachi, Takashi Noji +15
ARPES studies have established that the high- cuprates with single and double CuO layers evolve from the Mott insulator to the pseudogap state with a Fermi arc, on which t…
Pseudogap, Superconducting Gap, and Fermi Arc in High-Tc Cuprates Revealed by Angle-Resolved Photoemission Spectroscopy
Teppei Yoshida, Makoto Hashimoto, Inna M. Vishik +2
We present an overview of angle-resolved photoemission spectroscopy (ARPES) studies of high-temperature cuprate superconductors aiming at elucidating the relationship between the s…
Hidden self-energies as origin of cuprate superconductivity revealed by machine learning
Youhei Yamaji, Teppei Yoshida, Atsushi Fujimori +1
Experimental data are the source of understanding matter. However, measurable quantities are limited and theoretically important quantities are sometimes hidden. Nonetheless, recen…
Three-dimensional electronic structure of superconducting iron pnictides observed by angle-resolved photoemission spectroscopy
Walid Malaeb, Teppei Yoshida, Atsushi Fujimori +10
We have performed an angle-resolved photoemission spectroscopy (ARPES) study of the undoped and electron-doped iron pnictides BaFe2\_{-x}CoxAs2 (Ba122) (x=0, 0.14) and studied the…
