A perturbation method is used to study effective response of nonlinear Kerr composites, which are subject to the constitutive relation of electric displacement
The influence of decoherence on interference between two trapped Bose-Einstein condensates with arbitraryinitial states is studied. Analytic expressions of the
By means of improved ligand-field theory, the 'pure electronic' presure-induced shifts (PS's) and the PS's due to electron-phonon interaction (E
We study the eigenstate problem of a kind of coupled oscillators in the new quantum mechanical represen tation |q, μ, v〉, which is defined as the eigenvector o
