Model-mapped random phase approximation to evaluate superconductivity in the fluctuation exchange approximation from first principles
Hirofumi Sakakibara, Takao Kotani
We have applied the model-mapped RPA [H. Sakakibara et al., J. Phys. Soc. Jpn. 86, 044714 (2017)] to the cuprate superconductors La2CuO4 and HgBa2CuO4, resulting two-orbital Hubbar…
Numerical aspect of large-scale electronic state calculation for flexible device material
Takeo Hoshi, Hiroto Imachi, Akiyoshi Kuwata +3
Numerical aspects of large-scale electronic state calculation are explored on flexible organic device materials. Physical theory, numerical method and real application studies are…
EigenKernel - A middleware for parallel generalized eigenvalue solvers to attain high scalability and usability
Kazuyuki Tanaka, Hiroto Imachi, Tomoya Fukumoto +5
An open-source middleware EigenKernel was developed for use with parallel generalized eigenvalue solvers or large-scale electronic state calculation to attain high scalability and…
Calculation of large-aspect-ratio tokamak and toroidally-averaged stellarator equilibria of high-beta reduced magnetohydrodynamics via simulated annealing
M. Furukawa, Takahiro Watanabe, P. J. Morrison +1
A simulated annealing (SA) relaxation method is used for calculation of high-beta reduced magnetohydrodynamics (MHD) equilibria in toroidal geometry. The SA method, based on artifi…
Semileptonic decay of into , ,
Natsumi Ikeno, Melahat Bayar, Eulogio Oset
We study the semileptonic decay of meson into and the isospin zero , , resonances. We look at the react…
Constraining the optical potential in the search for eta-mesic 4He
M. Skurzok, P. Moslal, N. G. Kelkar +3
A consistent description of the $^{4}\hspace{-0.03cm}\mbox{He} η$ and (He) cross sections was recently propose…
