Formation and diffusion of a vacancy-polaron complex in olivine-type cathode-active materials, namely, LiMPO${}_{4}$ (M $=$ Fe, Mn), were theoretically investigated by using the first-principles density functional theory within a framework of GGA $+$

We theoretically study the spin multiplicity in the ground state of the square quantum dot (SQD) including four electrons, and discuss a possibility of the singlet‐triplet (S/T) instability in the quantum system. As predicted by Hund's rule, the gr

The magnetocrystalline anisotropy energy (MAE) of rare-earth transition-metal intermetallics ${R}_{2}{\text{Fe}}_{14}\text{B}$ ($R=\text{Nd}$, Gd, Y) was calculated by using the linear combination of pseudo-atomic-orbital method. Electronic structure

We investigate transport properties of Al monatomic wires at finite biases by means of Lippmann-Schwinger equations in the framework of the first-principles density functional theory. In order to clarify the effects of crystalline electrodes, the ele

It is well known that a flat plateau at 3.4 V appears in charging/discharging curve of olivine-type LiFePO4 cathode. The constant voltage indicates that the extraction/insertion proceeds under two-phase reaction in which the electrochemical potential

We present the first-principles investigations on π channel effects in electron transport properties of Al monatomic wires. By the eigenchannel decomposition technique, the transport properties are compared between three-atom and five-atom wires, sa

We theoretically studied the electronic structure of the three-dimensional spherical parabolic quantum dot (3D-SPQD) under a magnetic field. We obtained the quantum dot orbitals (QDOs) and determined the ground state by using the extended UHF approac
