In the present investigation, we study the reflection of plane waves, that is, Longitudinal displacement wave(P-Wave), Thermal wave(T-Wave) and Mass Diffusive wave(MD-Wave) in thermodiffusion elastic-half medium which is subjected to impedence boundary condition in context of one relaxatioon time theory given by Lord and Shulman theory (L-S) and the Coupled theory (C-T) of thermoelasticity. The...

We introduce a method to investigate the stability of wave-packet dynamics under perturbations of the Hamiltonian. Our approach relies on semiclassical approximations, but is nonperturbative. Two separate contributions to the quantum fidelity are identified: one factor derives from the dispersion of the wave packets, whereas the other factor is determined by the separation of a trajectory of th...

In this paper, a 16 channel 25 Gbps DWDM optical network is simulated and analyzed for 120 km using dispersion compensating fiber. The system is operated on -10dBm of Input Power. NRZ-DPSK modulation format is used for transmission under symmetrical compensation schemes. Group velocity and third order dispersion are compensated to improve the Q-factor. Impact of Third Order Dispersion as well a...

In this paper, we presents the quality factor evaluation of stimulated Raman scattering (SRS) and four wave mixing (FWM) in optical networks. The nonlinearity effect of stimulated Raman scattering (SRS) and four wave mixing (FWM) with 16-channel optical system. Two parameters are used to evaluate the performance of the optical passive networks. These parameters include transmitting power and qu...

We show that spin-density separation in a Bose gas is not restricted to 1D but also occurs in higher dimensions. The ratio (alpha) of the intraspecies atom-atom interaction strength to the interspecies interaction strength strongly influences the dynamics of spin-density separation and the elementary excitations. The density wave is phononlike for all values of alpha. For alpha < 1, the spin wa...

The electromagnetic form factors of the trinucleons 3H and 3He are calculated with wave functions obtained with the Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. Full account is taken of the two-body currents required by current conservation with the v18 interaction as well as those associated with N∆ transition currents and the currents of ∆ resonance components in the wave...

With a consistent definition of transverse-momentum-dependent(TMD) light-cone wave function of B-meson, we show that the amplitude of the radiative leptonic B-Decay can be factorized at one-loop level as a convolution with the wave function and a perturbative coefficient function, combined with a soft factor. In this TMD factorization, the transverse momenta of partons in the B-meson are taken ...

Liquid He is a model system for strongly correlated Fermi liquids. For this reason, many X-ray and neutron scattering experiments have been performed to understand the structure and dynamics of this quantum fluid. We have recently shown that two-dimensional liquid He sustains long-lived zero-sound excitations at large wave-vectors (Nature 483, 576, 2012). Here we show that its static structure ...

The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...
