Analytical approach to soliton ratchets in asymmetric potentials
(2005)
We use soliton perturbation theory and collective coordinate ansatz to investigate the mechanism of soliton ratchets in a driven and damped asymmetric double sine-Gordon equation. We show that, at the second order of the ...

Continuum discretization methods in a composite particle scattering off a nucleus: Benchmark calculations
(The American Physical Society, 2008)
The direct comparison of two different continuum discretization methods toward the solution of a composite particle scattering off a nucleus is presented. The first approach-the continuum-discretized coupled-channel method-is ...
