چکیده
In this paper, we use a straightforward numerical method to solve scattering models in one-dimensional lattices based on tight-binding band structure. We do by using the wave packet approach scattering, which presents more intuitive physical picture than traditional plane approach. Moreover, general matrix diagonalization that is easily accessible undergraduate students taking first course quantum mechanics used. Beginning with brief review of transport continuum limit, comparisons are made its counterpart lattice. The results obtained through then benchmarked against analytic results. case resonant dimer investigated lattice, and several values mean momentum identified. transmission coefficients for incident step potential rectangular barrier compared investigating an equivalent scenario Finally, present short simulations process, emphasize how simple methodology can be used visualize some remarkable phenomena.

Fast methods for inverse wave scattering problems
Inverse wave scattering problems arise in many applications including computerized/diffraction tomography, seismology, diffraction/holographic grating design, object identification from radar singals, and semiconductor quality control. Efficient algorithms exist for some inverse wave scattering problems in the low-and high-frequency regime or with weak scatterers. However, inverse wave scatteri...
متن کاملReal Time Single Scattering Effects
Rendering mist, haze or fog remains a challenge in current computer graphics since it is intrinsically a 3D problem. While the attenuation caused by fog is easy to implement, single scattering effects such as glows and shafts of light, that increase considerably the realism, are harder to render in realtime. This paper addresses the rendering of such effects along with volumetric shadows induce...
متن کاملPhoton plasma–wave interaction via Compton scattering
The Kompaneets theory of photon kinetic evolution due to the Compton effect in the absence of absorption and emission is extended to the case of the Vlasov plasma wave oscillations. Under the assumption that the electron distribution function at equilibrium is perturbed by a solution of the linearised Vlasov equation in the long-wavelength limit, a solution of the Kompaneets kinetic equation fo...
متن کاملWave packet spreading and localization in electron-nuclear scattering.
The wave packet molecular dynamics (WPMD) method provides a variational approximation to the solution of the time-dependent Schrödinger equation. Its application in the field of high-temperature dense plasmas has yielded diverging electron width (spreading), which results in diminishing electron-nuclear interactions. Electron spreading has previously been ascribed to a shortcoming of the WPMD m...
متن کاملTime Dependent Wave Packet Study of the H-+ H2 Nonreactive Scattering
Time dependent wave packet calculations have been performed for the H + H2 nonreactive scattering, summed of elastic and inelastic probabilities, on the recent reported potential energy surface of the 3 H systems. The total probabilities for total angular momentum J up to 35 have been calculated to get the converged integral cross sections over collision energy range of 0.20 1.42 eV. Integral...
