Fluctuation exchange study on the electron-hole asymmetry of the superconductivity across 1/3 filling in the trilayer Hubbard model
Yushi Yamada, Masataka Kakoi, Masayuki Ochi +1
We study within the fluctuation exchange approximation the trilayer Hubbard model where three layers of the Hubbard model are coupled by large interlayer hoppings so that the overl…
Study on the validity of IPT+parquet method as an impurity solver in DMFT focusing on orbital fluctuations
Aira Yamada, Ryota Mizuno, Masayuki Ochi +2
A breakdown of calculations with exact impurity solvers in the dynamical mean field theory in multiband systems easily occurs due to the expensive numerical cost. To overcome this…
Improvement of the simplification method for the local two-particle full-vertex towards precise frequency behavior
Ryota Mizuno, Kazuhiko Kuroki, Masayuki Ochi
Estimating the local two-particle vertex functions, which are crucial for capturing the spatial fluctuation of the effective field beyond the single-site DMFT, is still challenging…
Nonreciprocal charge transport in polar Dirac metals with tunable spin-valley coupling
M. Kondo, M. Kimata, M. Ochi +7
Nonreciprocal charge transport in solids, where resistance is different between rightward and leftward currents, is a key function of rectifying devices in the modern electronics,…
Anomalous Fermi pockets on Hund's metal surface of Sr2RuO4 induced by the correlation-enhanced spin-orbit coupling
Takeshi Kondo, Masayuki Ochi, Shuntaro Akebi +4
The electronic structure of the topmost layer in Sr2RuO4 in the close vicinity of the Fermi level is investigated by angle-resolved photoemission spectroscopy (ARPES) with a 7-eV l…
