Excitron-Induced Pair Fluctuations Reveal Superconductivity in the Electron Gas
Yasutami Takada
Understanding how superconductivity can emerge in dilute electronic systems remains a central challenge in condensed matter physics. By performing first-principles calculations of…
Low-energy peak in the one-particle spectral function of the electron gas at metallic densities
Yasutami Takada
Based on a nonperturbative scheme to determine the self-energy Σ(k,iw_n) with automatically satisfying the Ward identity and the total momentum conservation law, a fully self-consi…
On-Top Density in the Nonlinear Metallic Screening and its Implication on the Exchange-Correlation Energy Functional
Yasutami Takada
In comparison with the accurate data on the on-top electron density n(0) in the proton-embedded electron gas with the density parameter r_s in the range 1-12 obtained by diffusion…
Emergence of an excitonic collective mode in the dilute electron gas
Yasutami Takada
By comparing two expressions for the polarization function given in terms of two different local-field factors, G_+(q,iw) and G_s(q,iw), we have derived the kinetic-energy-fluctuat…
Theory for Reliable First-Principles Prediction of the Superconducting Transition Temperature
Yasutami Takada
A review is given for the theoretical framework to give a reliable prediction of the superconducting transition temperature Tc from first principles, together with a practical stra…
Theory of Superconductivity in Graphite Intercalation Compounds
Yasutami Takada
On the basis of the model that was successfully applied to KC8, RbC8, and CsC8 in 1982, we have calculated the superconducting transition temperature Tc for CaC6 and YbC6 to find t…
