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…
Electronic band structure, phonon dispersion, and magnetic triple-q state in GdGaI
Tatsuya Kaneko, Ryota Mizuno, Shu Kamiyama +2
We theoretically investigate the physical properties of the magnetic van der Waals material GdGaI. Using first-principles calculations, we compute the phonon dispersion of GdGaI an…
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…
