The existence of an absolute photonic bandgap in the near-infrared for two-dimensional periodic dielectric structures is discussed for photons propagating in the plane of such 2D crystals. A special emphasis is put on the influence of the shape and s

We investigate in this paper different aspects of the absolute photonic bandgap (PBG) formation for a two-dimensional periodic dielectric structure. In particular we examine how the symmetry of the filling pattern in a periodic dielectric material in

Ce calcul utilise un modele de fonctionnelle de densite locale et une approximation d'auto-energie de quasi-particule avec une matrice dielectrique locale ecrantee statiquement. Le terme d'interaction spin-orbite est evalue dans la theorie des pertur

The second- and third-order rearrangement contributions to the single-particle energies in $^{16}\mathrm{O}$ are calculated microscopically using the Sprung-de Tourreil force. The $s$-state second-order rearrangement has been evaluated by an energy-a

In this work we study the properties of the collective modes in nuclear matter in the four available longitudinal channels. For the calculations we selected tour different effective interactions. The particularly successful one was the finite-range i

Self-consistent calculations are performed in 16O with effective G matrices obtained from two different soft core interactions. The calculations possess the 'triple' self-consistency: (a) on the single particle basis, (b) on the single particle eigen

We present new integrals of motion for the Toda lattice (chain of particles in one dimension with exponential interaction) for two special cases of boundary conditions: the free‐end lattice with three non‐equal‐mass particles and the fixed‐en

In this work the hydrodynamic approximations in the cold nuclear matter are analyzed and compared to the zero sound solution in the long wavelength limit. It is shown that the hydrodynamical hierarchy can reasonably approximate the zero sound solutio

Both the third-order and the second-order rearrangemetn corrections are included in a self-consistent calculation of the single-particle field of $^{16}\mathrm{O}$, carried out with a model $G$ matrix derived from the soft-core Sprung-de-Tourreil int

We present for the first time a calculation of the one-electron excitations of gallium arsenide that explicitely accounts for the exchange nonlocality. The calculation has been performed in two steps: (1) An exact valence electron Hartree–Fock comp
