Two-orbital Kondo effect in quantum dot coupled to ferromagnetic leads

Hitoshi Yoshizumi, Kensuke Inaba, Tomoko Kita +1

We study the Kondo effect of a two-orbital vertical quantum dot (QD) coupled to two ferromagnetic leads by employing an equation of motion method. When the ferromagnetic leads are…

Numerical-Diagonalization Study of Spin Gap Issue of the Kagome Lattice Heisenberg Antiferromagnet

Hiroki Nakano, Toru Sakai

We study the system size dependence of the singlet-triplet excitation gap in the kagome-lattice Heisenberg antiferromagnet by numerical diagonalization. We successfully obt…

Frustration-Induced Ferrimagnetism in S=1/2 Heisenberg Spin Chain

Tokuro Shimokawa, Hiroki Nakano

The ground-state properties of the S=1/2 frustrated Heisenberg spin chain with interactions up to fourth nearest neighbors are investigated by the exact-diagonalization method and…

Critical magnetization behaviors of the triangular and Kagome lattice quantum antiferromagnets

Toru Sakai, Hiroki Nakano

We investigate the quantum spin antiferromagnets on the triangular and Kagome lattices in magnetic field, using the numerical exact diagonalization. Particularly we focus o…

Collapse of Ferrimagnetism in Two-Dimensional Heisenberg Antiferromagnet due to Frustration

Hiroki Nakano, Tokuro Shimokawa, Toru Sakai

We study ferrimagnetism in the ground state of the antiferromagnetic Heisenberg model on the spatially anisotropic kagome lattice, in which ferrimagnetism of the conventional Lieb-…
