Relativistic density functional theory with finite-light-speed correction for the Coulomb interaction: a non-relativistic-reduction based approach
Tomoya Naito, Ryosuke Akashi, Haozhao Liang +1
The Breit correction, the finite-light-speed correction for the Coulomb interaction of the electron-electron interaction in , is introduced to density fu…
Archetypical "push the band critical point" mechanism for peaking of the density of states in three-dimensional crystals: Theory and case study of cubic HS
Ryosuke Akashi
The point of zero gradient of the electronic band structure--critical point--generally induces the singularity in the density of states (DOS), but no isolated critical point yields…
AtomREM: Non-empirical seeker of the minimum energy escape paths on many-dimensional potential landscapes without coarse graining
Yuri S. Nagornov, Ryosuke Akashi
Recently a non-empirical stochastic walker algorithm has been developed to search for the minimum-energy escape paths (MEP) from the minima of the potential surface [J. Phys. Soc.…
Coulomb Energy Density Functionals for Nuclear Systems: Recent Studies of Coulomb Exchange and Correlation Functionals
Tomoya Naito, Ryosuke Akashi, Gianluca Colò +2
The Coulomb exchange and correlation energy density functionals for electron systems are applied to nuclear systems. It is found that the exchange functionals in the generalized gr…
Completing density functional theory by machine-learning hidden messages from molecules
Ryo Nagai, Ryosuke Akashi, Osamu Sugino
Kohn-Sham density functional theory is the base of modern computational approaches to electronic structures. Their accuracy vitally relies on the exchange-correlation energy functi…
