摘要:Novel ternary Laves phase compounds were explored, and Mg2Ir3Si was synthesized via a solid-state reaction. X-ray diffraction studies revealed that Mg2Ir3Si crystallizes in a Mg2Cu3Si-type structure ( P 63...

摘要:Hierarchical equations of motion approach with the Drude–Lorentz spectral density has been widely employed in investigating quantum dissipative phenomena. However, it is often computationally costly for low-temperature systems because a number of Matsubara frequencies are in...

摘要:We have succeeded in synthesizing electron-doped polycrystalline bulk samples of T′-La1.8Eu0.2CuO4− y F y ( y = 0–0.15) by the fluorination of undoped (Ce-free) T′-La1.8Eu0.2CuO4 usi...

摘要:We investigate the stability of multiple- Q spiral states in d – p electron systems with the strong spin–charge coupling. By using variational calculations on a square lattice, we find that the double- Q state with the scalar chirality density wave, which has been studied in...

摘要:Under investigation in this work is the Kundu-nonlinear Schrödinger equation, which can be reduced to the standard nonlinear Schrödinger equation. Through the Darboux-dressing transformation, we obtain and discuss the localized wave solutions of the equation. This family of ...

摘要:We theoretically investigate the effective exchange interaction, J eff, mediated by conductive electrons within a nonmagnetic metal spacer, in the presence of a bias voltage, sandwiched by two ferromagnetic insulators. On the basis of the tight-binding model, we show t...

摘要:We clarify the macroscopic symmetry and microscopic model-parameter conditions for emergence of spin-split electronic band structure in collinear antiferromagnets without atomic spin–orbit coupling. By using the microscopic multipole descriptions, we elucidate the fundamenta...
