A Soliton Pulse Engine in the Lattice Field Medium: Controlled Nucleation, Directional Guidance, and Momentum Transfer via Adaptive Field Configurations
Year: 2026
Type: preprint
Abstract: This paper presents a numerical study of a controlled soliton nucleation and steering protocol in a discrete coupled scalar field lattice on a periodic 48³ grid. Using the 27-point isotropic stencil, periodic parametric bursts are applied to drive modulational instability and nucleate localized structures, while engineered χ-gradient channels provide directional bias for steering. Individual solitons are identified and tracked via intensity-weighted center-of-mass trajectories, enabling direct measurement of vectorial drift velocities and steering performance. A three-dimensional variational analysis with Gaussian trial functions confirms stability parameters, and the practical importance of a non-canonical Ginzburg–Landau saturation term is demonstrated through control experiments. Results show reliable soliton formation and measurable directional motion in the later stages of long simulations. All findings are model-specific and exploratory; the complete simulation code is provided in the appendix.
