Emergence of a Kondo singlet state with Kondo temperature well beyond 1000 K in a proton-embedded electron gas

Takada Yasutami , Maezono Ryo , Yoshizawa Kanako

… the use of LDA and diffusion Monte Carlo simulations with the total electron number up to 170, we obtain a complete picture of the transition, in particular, a sharp transition from short-range H^+ screening charge resonance to long-range Kondo-type spin-singlet resonance, the emergence of which is confirmed by the presence of an anomalous Friedel oscillation characteristic to the Kondo singlet state with the Kondo temperature T_K well beyond 1000 …

Laser-Induced Kondo Effect in Ultracold Alkaline-Earth Fermions.

Nakagawa Masaya , Kawakami Norio

… We demonstrate that laser excitations can coherently induce a novel Kondo effect in ultracold atoms in optical lattices. … Using a model of alkaline-earth fermions with two orbitals, it is shown that the optically coupled two internal states are dynamically entangled to form the Kondo-singlet state, overcoming the heating effect due to the irradiation. …

A Model Study of Raman Spectra Displaying the Interplay between the Kondo Effect and the Magnetic Correlation in HFS

BARAL Purna C. , ROUT Govind C. , B.J.B. Junior College , Condensed Matter Physics Group F.M. University

… The system is described by model Hamiltonian consisting of the hopping of the conduction and f-electrons in addition to the Kondo exchange interaction in presence of the spin-spin interaction of f-electrons. … The Hamiltonian is treated in mean-field approximation to find the Kondo singlet parameter λ and the short-ranged f-electron correlation parameter Γ. …

Effects of localized spins on excitons in single-walled carbon nanotubes with imperfections

Konabe Satoru , Okada Susumu , 岡田晋

… We show that the interaction can be written as the spin–spin interaction expressed by the Kondo-like Hamiltonian. … Our calculation reveals that the interaction induces mixing between the singlet and triplet excitons and that this mixing produces optically activated triplet excitons. …
