We study the influence of laser profile on the linewidth of the optical spectrum of multi-photon resonance phenomena. First, we investigate the dependence of the absorption spectrum …
We report on the existence and stability of defect gap solitons in real linear periodic optical lattices with parity-time (PT)-symmetric nonlinear potentials. For uniform real periodic optical …
We present the experimental generation of twin Airy beams with a phase insensitive parametric amplifier, which is based on a four-wave mixing process assisted by active Raman gain …
In this paper we report new numerical results on the disordered Schrödinger equation with nonlinear hopping. By using a classical harmonic Hamiltonian and the Su–Schrieffer–Heeger …
Infanticide Bill, 1938, 172 Infantile paralysis, as result of injury, 407 Inflammation of sinovial lining of wrist joint and tendon sheaths, 251 Injury, accidental, definition of, 300-and disease, …
The Pnma incommensurate phase transition in the perovskite Pr 0.48 Ca 0.52 MnO 3 at ∼ 235 K is accompanied by shear strains of up to ∼ 2.5% (from neutron diffraction) and …
The elastic properties of fcc Fe–Mn–X (X = Cr, Co, Ni, Cu) alloys with additions of up to 8 at.% X were studied by combinatorial thin film growth and characterization and by ab initio …
We report the observation of correlated photon fluctuations over a narrow range of current at threshold of an interband cascade laser using single-detector photon noise measurements. …
The theoretical and experimental study of the role of incident polarization in THz transmission through the hole array is presented in this paper. First, the detailed theoretical …
A theory of a closed contour scheme of excitation (Δ-scheme) of a three-level atom in an optically dense medium taking into account the effect of temperature is presented. It is shown …
