We report an experimental study of group-velocity dispersion effect on an entangled two-photon wavepacket, generated via spontaneous parametric downconversion and propagating through a dispersive medium. Even in the case of using CW laser beam for pump, the biphoton wavepacket and the secondorder

Abstract: We show that phase space methods are effective in understanding wave and noise propagation in a dispersive medium. The phase space distributions we use are the Wigner distributions of position and wave number or time and frequency. In addition, we show that the Wigner distribution offers

Abstract. The concept of soliton complex in a nonlinear dispersive medium is proposed. It is shown that strongly interacting identical topological solitons in the medium can form bound soliton complexes which move without radiation. This phenomenon is considered to be universal and applicable

qualitative, symmetry dependent, features of Brillouin scattering by an interface vacuum- cubic dispersive medium. The peak due to Rayleigh wave is shown to be unaffected by exciton polariton formation. Spatial dispersion (SD) effects due to wavevector dependence of the dielectric function have been

Abstract. A theoretical evaluation for the degree of temperature and humidity effects of dispersion medium on the evolution of liquid-drop aerosol parameters was represented in this work. A series of experiments to investigate parameters of aerosol media at different humidity and temperature

Abstract—Electric permittivity and magnetic permeability of linear passive dispersive medium were defined using the circuit equation of an electrically small antenna (scatterer) with resonant and antiresonant properties. It was shown that the average macroscopic energy stored by the scatterers

Factors that affect he probability of genetic transformation f Escherichia coli by plasmids have been evaluated. A set of conditions is described under which about one in every 400 plasmid molecules produces a transformed cell. These conditions include cell growth in medium containing elevated
