Microscopic analysis of a correlation between dipole transitions and in spherical nuclei
Correlation between B() and B() values are considered within microscopic QRPA approach. General
arguments for a dependence of a ratio between these values on a collectivity of
the and phonons and ground state correlations are provided.Comment: 2 page

Quantum Size Effect in Conductivity of Multilayer Metal Films
Conductivity of quantized multilayer metal films is analyzed with an emphasis
on scattering by rough interlayer interfaces. Three different types of quantum
size effect (QSE) in conductivity are predicted. Two of these QSE are similar
to those in films with scattering by rough walls. The third type of QSE is
unique and is observed only for certain positions of the interface. The
corresponding peaks in conductivity are very narrow and high with a finite
cutoff which is due only to some other scattering mechanism or the smearing of
the interface. There are two classes of these geometric resonances. Some of the
resonance positions of the interface are universal and do not depend on the
strength of the interface potential while the others are sensitive to this
potential. This geometric QSE gradually disappears with an increase in the
width of the interlayer potential barrier.Comment: 12 pages, 10 figures, RevTeX4, to be published in Phys. Rev B (April

Optical chaos in nonlinear photonic crystals
We examine a spatial evolution of lightwaves in a nonlinear photonic crystal
with a quadratic nonlinearity when simultaneously a second harmonic and a
sum-frequency generation are quasi-phase-matched. We find the conditions of a
transition to Hamiltonian chaos for different amplitudes of lightwaves at the
boundary of the crystal.Comment: LaTEX2e, 5 pages, 4 figure
