Self-consistent orbital-free nuclear density functional theory with a physics-constrained learned nonlocal kinetic energy functional
Fumihiro Imoto
Nonlocal kinetic-energy density functionals (KEDFs) can encode nuclear shell structure in orbital-free density functional theory (OFDFT), but self-consistency requires accurate fun…
Semilocal exchange functionals from the exact-exchange condition for the hydrogen atom: Hydrogenic exactness and recovery of Rydberg-like bound states
Fumihiro Imoto
In semilocal density functionals the exchange potential decays too rapidly outside atoms and molecules and lacks the correct tail; as a consequence, functionals from PBE to…
Analytic structure and asymptotic analysis of screened second-order exchange in the uniform electron gas
Fumihiro Imoto
The uniform electron gas underlies the local-density approximation of density-functional theory, yet correlation contributions beyond the random-phase approximation (RPA) are known…
Unified description of cuprate superconductors by fractionalized electrons emerging from integrated analyses of photoemission spectra and quasiparticle interference
Shiro Sakai, Youhei Yamaji, Fumihiro Imoto +6
Electronic structure of high-temperature superconducting cuprates is studied by analyzing experimental data independently obtained from two complementary spectroscopies, one, quasi…
