In this article, the coupling equations of the laser, the first Stokes, the first anti-Stokes light, and the coherent phonon field are derived from the hamiltonian with the relaxation and dissipation terms introduced phenomenologically. The properties of these equations are analysed by adopting an approximation higher than the quasi-static approximation, provided the molecules are far from resonan...
A new representation of (real and virtual) localized modes in the solid state problems is formulated by considering P(z), the modified resolvent operator. It has singularities on the real axis of the z plane only. The isolated poles correspond to real localized modes. When P(E+iη) is analytically continuated onto the second Riemann surface (η > 0), its complex poles correspond to virtual (or unsta...
By utilizing the LT representation and considering the effect of spin-spin interaction in the d3 configuration, the authors calculated the zero-field splitting of ground state in ruby and obtained a result of 2D =-0.12 cm-1 for the zero-field splitting.
The chemical etching method is used to reveal dislocations produced by indentation on silicon single crystal specimens. Edge (or 60°) dislocation velocities are measured under different shear stresses and at different temperatures (700-900℃). By assuming that the motion is thermally activated, the corresponding activation energy is obtained to be ~2.94 eV. Velocities of edge (or 60°) dislocations ...
In this paper the induced uniaxial magnetic anisotropy of ferrites containing Co2+ and Ni2+ is discussed. For the former case, it starts from the mechanism proposed by Iida, taking into account the influence of cation vacancy upon the energy levels and wave functions of Co2+; while for the latter case, it is based upon the mechanism introduced by Schnettler-Gyorgy, considering the Jahn-Teller effe...
It is assumed that the vector meson φ is a resonance which is formed of the KK scattering by exchange of ρ, ω and φ itself. The method of N/D of the double dispersion relation is used and the experimental values of the masses are known for the ρ, ω and exchanged φ. The partial wave amplitude of the KK scattering is given approximately. When it is required for the partial wave amplitude to give in ...
In this paper, the general form of the Regge representation of the scattering amplitude has been established as where Pl(μ,ν)(z) is the Jacobi function. The relationship between such a representation and the usual Regge representation has been studied in detail. Some properties of the Jacobi functions are discussed in the appendix.
Energy levels corresponding to ligand field transition bands of complex ions CuX4-(X = Cl, Br) were given. The quantitative relation between positions of absorption bands and structures of these complex ions was deduced. Calculation results agree with experimental findings.
