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…
Theoretical study of superconductivity in freestanding infinite-layer nickelate membranes under pressure: mitigation of excess correlation enhances
Mahiru Seki, Reo Kono, Naotaka Tanaka +5
We theoretically investigate a freestanding membrane of infinite-layer nickelate NdSrNiO under pressure by constructing a seven-orbital effective model based…
Nonlinear phononics in LaFeAsO: Optical control of the crystal structure toward possible enhancement of superconductivity
Shu Kamiyama, Tatsuya Kaneko, Kazuhiko Kuroki +1
Nonlinear phononics provides a route to control crystal structures through light-induced phonon excitation. In this study, we apply nonlinear phononics to an iron-based superconduc…
