Quantum geometry and RKKY in flat bands
Chang-geun Oh, Makoto Shimizu, Youichi Yanase +1
Flat conduction bands quench the group velocity and thus challenge conventional, dispersion-driven pictures of the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, where localized…
Magnetic fluctuations driven by quantum geometry
Makoto Shimizu, Chang-guen Oh, Youichi Yanase
Using quantum distance, magnetic susceptibility in the noninteracting limit can be rigorously split into two contributions: one arises solely from band dispersion while the other s…
Magnetic fluctuations and anisotropy in UTe2: a multi-orbital study based on GGA+U and RPA
Makoto Shimizu, Youichi Yanase
Pressure-induced changes in the magnetic and superconducting properties of a spin-triplet superconductor candidate UTe have attracted considerable interest, underscoring the ne…
Multilayer Crystal Field states from locally broken centrosymmetry
Owen Moulding, Makoto Shimizu, Amit Pawbake +9
Local charge, spin, or orbital degrees of freedom with intersite interactions are oftentimes sufficient to construct most quantum orders. This is conventionally true for f-electron…
Well-posedness of Heat Equations with Nonlinearities of Arbitrarily Rapid Growth
Yohei Fujishima, Kotaro Hisa, Robert Laister
We address local- and global-in-time well-posedness of the Cauchy problem for nonlinear heat equations without imposing growth rate restrictions on the nonlinearity a priori. Our r…
