A Novel Pseudo-Spectral Time-Domain Theory of Magnetic Neutron Scattering Illustrated Using A Uniformly Magnetized Sphere
Kun Chen
A universal numerical method is developed for the investigation of magnetic neutron scattering. By applying the pseudospectral-time-domain (PSTD) algorithm to the spinor version of…

A General PSTD Method to Solve Quantum Scattering in the Fresnel and Far-field regions by A Localized Potential of Arbitrary Form
Kun Chen
We present a time domain method to solve quantum scattering by an arbitrary potential of finite range. The scattering wave function in full space can be obtained, including the nea…
