摘要:We have investigated the characteristics of multi-photon absorption (MPA) in a β-Ga2O3 single crystal at room temperature using the photoluminescence (PL) of the self-trapped exciton (STE) as a probe. From analysis of the excitation fluence dependence o...

摘要:We study a topological phase diagram of a ferromagnetic topological nodal semimetal. We consider a lattice model for three dimensional topological insulators with ferromagnetic ordering. The exchange coupling between the magnetization and the electron spin leads to the nodal band...

摘要:We calculate the temperature dependence of the heat capacity per spin, C ( T ), for quantum and classical Kitaev-Heisenberg (qKH and cKH, respectively) models on a honeycomb lattice. In the qKH model, C ( T ) shows two peaks in the magnetically ordered phase near the Kitaev spin-...

摘要:The one-dimensional Heisenberg antiferromagnets of large-integer- S spins are studied; their Haldane gaps are estimated by the numerical diagonalization method for S = 5 and 6. We successfully obtain a monotonically increasing sequence of finite-size energy difference data c...

摘要:We report 75As-NMR/NQR results on new iron-arsenide compounds (La0.5− x Na0.5+ x )Fe2As2. The parent compound x = 0 exhibits a stripe-type antiferromagnetic (AFM) order below T N = 130 K. The measur...

摘要:A chemical-impurity substitution in a geometrical spin-frustrated antiferromagnet often produces an unconventional antiferromagnetic state, because the ground states of the pure systems maintain a delicate balance among the spins. To investigate the changes introduced by ran...

摘要:The density of states of the disordered s-wave superconductor is calculated perturbatively. The effect of Coulomb interaction on diffusively moving electrons in the normal state has been known before, but in the superconducting state both diffuson and the screened Coulomb interac...

摘要:We report on self-assemblies formed from spherical patchy particles interacting by a long-range attraction through a patch region in a two-dimensional system. We performed Monte Carlo simulations to find stable structures in a system with constant number of particles under c...

摘要:We developed and implemented the van der Waals density functional with noncollinear magnetism. To demonstrate the validity of the current implementation, we applied the method to the β-phase of solid oxygen having spins with 120° spin orientation. We show that the van der Wa...
