Theoretical designing of multiband Nickelate and Palladate superconductors with configuration
Naoya Kitamine, Masayuki Ochi, Kazuhiko Kuroki
In a previous study, we proposed a possibility of high superconductivity in mixed-anion nickelates with electron configuration. The theory was based on the fact tha…
Possible high Superconductivity in LaNiO under High Pressure through Manifestation of a Nearly-Half-Filled Bilayer Hubbard Model
Hirofumi Sakakibara, Naoya Kitamine, Masayuki Ochi +1
Inspired by a recent experiment showing that LaNiO exhibits high superconductivity under high pressure, we theoretically revisit the possibility of superconductiv…
Electron-hole dichotomy and enhancement of thermoelectric power factor by electron-hole-asymmetric relaxation time: a model study on a two-valley system with strong intervalley scattering
Masayuki Ochi
The role of electron-phonon scattering in thermoelectric transport has been paid much attention, especially in multivalley systems. By investigating a two-valley model with electro…
Spin-polarized saddle points in the topological surface states of the elemental Bismuth revealed by a pump-probe spin-resolved ARPES
Yuto Fukushima, Kaishu Kawaguchi, Kenta Kuroda +11
We use a pump-probe, spin-, and angle-resolved photoemission spectroscopy (ARPES) with a 10.7 eV laser accessible up to the Brillouin zone edge, and reveal for the first time the e…
TC++: First-principles calculation code for solids using the transcorrelated method
Masayuki Ochi
TC++ is a free/libre open-source software of the transcorrelated (TC) method for first-principles calculation of solids. Here, the TC method is one of the promising wave-function t…
Superconductivity in a Magnetic Rashba Semimetal EuAuBi
Hidefumi Takahashi, Kazuto Akiba, Masayuki Takahashi +4
We report the observation of superconductivity with multiple magnetic ordering and Rashba-type spin-orbit coupling in a layered polar semimetal EuAuBi. Magnetic transition is obser…
