Scattering problems via real-time wave packet scattering [PDF]
American Journal of Physics, 2021 In this paper, we use a straightforward numerical method to solve scattering models in one-dimensional lattices based on a tight-binding band structure. We do this by using the wave packet approach to scattering, which presents a more intuitive physical picture than the traditional plane wave approach.

A Quantum Scattering Interferometer [PDF]
, 2007 The collision of two ultra-cold atoms results in a quantum-mechanical superposition of two outcomes: each atom continues without scattering and each atom scatters as a spherically outgoing wave with an s-wave phase shift.

Rigorous analysis of extremely asymmetrical scattering of electromagnetic waves in slanted periodic gratings [PDF]
, 2001 Extremely asymmetrical scattering (EAS) is a new type of Bragg scattering in thick, slanted, periodic gratings. It is realised when the scattered wave propagates parallel to the front boundary of the grating.

Scattering amplitude from Bethe-Salpeter wave function inside the interaction range [PDF]
, 2018 We propose a method to calculate scattering amplitudes using the Bethe-Salpeter wave function inside the interaction range on the lattice. For an exploratory study of this method, we evaluate a scattering length of $I=2$ S-wave two pions by the use of ...

Raman gain against a background of non-thermal ion fluctuations in a plasma [PDF]
, 2000 A complex stimulated Raman scattering event against a background of non-thermal ion acoustic waves in an inhomogeneous plasma is described. We obtain analytic forms for the Raman gain due to a five-wave interaction consisting of conventional three-wave ...
