The recent rise of material platforms combining magnetism and two-dimensionality mobile carriers reveals a diverse spectrum spin-orbit phenomena stimulates its ongoing theoretical discussions. In this paper, we use the density matrix approach to provide unified description subtle microscopic effects governing electron gas spin behavior in clean limit upon electric perturbations two-dimensional ...

in this research we work with the effective hamiltonian and the quark model. we investigate the decay rates of matter-antimatter of quark. we describe the effective hamiltonian theory and apply this theory to the calculation of current-current ( ), qcd penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. the gluonic penguin structure of hadronic decays is studied through th...

and Applied Analysis 3 Proof. The proof follows from Theorem 2.1. The following theorem shows that on a slowly oscillating compact subset A of R, slowly oscillating continuity implies uniform continuity. Theorem 2.3. Let A be a slowly oscillating compact subset of R and let f : A → R be slowly oscillating continuous on A. Then f is uniformly continuous on A. Proof. Assume that f is not uniforml...

In this paper, we consider the Robinson-Schensted correspondence for oscillating tab-leaux and skew oscillating tableaux deened in 15] and 3]. First we give an analogue, for the oscillating tableaux, of the classical geometric construction of Viennot for standard tableaux ((16]). Then, we extend a construction of Sagan and Stanley ((10]), dealing with standard tableaux and skew tableaux, to ded...

Abstract It is well known that the linear and nonlinear light reflection transmission formula can be obtained from standard macroscopic Maxwell equation. In past, a microscopic approach based on Ewald–Oseen extinction theorem to derive by direct dipole summation has been performed Fearn et al where they successfully derived Fresnel in optics. this work, we extend their work for first time of an...

Studies of the nonlinear Faraday effect (rotation of the plane of polarization in a longitudinal magnetic field) on resonance atomic transitions have been reported in a number of theoretical and experimental papers [1-9]. The nonlinear effect manifests itself at moderate laser intensities in the absence of atomic collisions. It leads to narrow peaks in the magnetic field dependence of Faraday r...

The authors present a simple configuration for dual-oscillating lasers gain control erbium-doped fiber amplifier (EDFA) in which dual-oscillating lasers are formed by two pairs of fiber Bragg gratings (FBGs). Experimental results show that dual-oscillating lasers dramatically reduce steady and transient gain variations caused by spectral hole burning and relaxation oscillations, and the dual-os...

the ultraviolet-visible (uv) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. the electric dipole moments and polarizabilities in the molecular excited electronic states were determined. it was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

Classical trajectory (Monte Carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the H¯+C2H2 system. The method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. It is also assumed that the colliding particles have a d...
