Defect induced wave-packet dynamics in linear one-dimensional photonic lattices
(Physica Scripta, 2015)
We study numerically light beam propagation across uniform, linear, one-dimensional photonic lattice possessing one nonlinear defect. Depending on the strength of nonlinear defect, input beam position and phase shift, ...
Effect of wave damping on the nonlinear saturation of stimulated Raman scattering in a finite homogeneous plasma
(Physica Scripta, 1996)
A question of stationarity of a nonlinear saturated regime of stimulated Raman backscattering in a finite homogeneous plasma is considered. Slowly varying envelope equations with the damping and the nonlinear frequency ...
Feasibility of the elliptic flow measurements in pp"LHC using the Lee-Yang zero method
(Physica Scripta, 2014)
This paper presents the results of an attempt to measure the elliptic flow in the smallest collision system (pp) at the highest designed collision energy at the Large Hadron Collider (LHC) using the genuine collective ...
On the axial variation of the electron density in a plasma column of the surfatron type
(Physica Scripta, 1997)
This paper deals with the axial structure of the electron density in the central portion of a plasma of the surfatron type. The point of departure is an expression for the attenuation coefficient which includes the dielectric ...
Lattice relaxation around arsenic and selenium in CdTe
(Physica Scripta, 2005)
We have investigated the lattice relaxation around impurity atoms at the anion sublattice in CdTe, such as As acting as acceptor and Se which is isovalent to Te, with fluorescence detected EXAFS. We experimentally verify ...
On the determination of the time-scale of three-fragment emission in the 12.7 GeV He-4+U-238 reaction using the polycarbonate track detector Makrofol
(Physica Scripta, 2011)
The timescale for emission of three fragments (Z GT = 8) in the 12.7 GeV He-4+U-238 reaction has been studied using a sandwich configuration of the Makrofol polycarbonate track detector. In events with varying multiplicity ...
Biomechanical model produced from light-activated dental composite resins: a holographic analysis
(Physica Scripta, 2013)
Light-activated dental composites, commonly applied in dentistry, can be used as excellent material for producing biomechanical models. They can be cast in almost any shape in an appropriate silicone mold and quickly ...
Up-conversion luminescence of Tm3+ sensitized by Yb3+ ions in GdVO4
(Physica Scripta, 2013)
The aim of this work is to study up-conversion (UPC) luminescence in a series of Tm3+/Yb3+-co-doped GdVO4 samples synthesized by the solid-state method. The concentrations of Yb3+ ions were 3, 6 and 9 mol.%, while the ...
Low-temperature effects on up-conversion emission of Er3+/Yb3+-co-doped Y2O3
(Physica Scripta, 2013)
Over the past few years, rare-earth-ion-doped materials have attracted a great deal of interest due to their potential application as optical temperature sensors. The luminescence properties of these materials are sensitive ...
Rare earth (Sm3+ and Dy3+)-doped gadolinium oxide nanomaterials for luminescence thermometry
(Physica Scripta, 2013)
The possibility of using Sm3+- and Dy3+-doped Gd2O3 nanopowders as thermographic phosphor materials was studied. Both samples were synthesized by a combustion method. The crystalline structure of synthesized samples was ...
