RDT Kernel is a physics-inspired numerical simulator implementing a nonlinear partial differential equation (PDE) for a scalar field L(x, y, t). It combines a logarithmic damping term with a Laplacian diffusion term, forming a compact PyTorch-based solver for recursive field dynamics, entropy stabilization, and nonlinear diffusion behavior.
This implementation uses PyTorch tensor operations, automatically runs on CPU or GPU (and TPU if available), and can function as a standalone simulator or a physics-based component within other systems.
The kernel evolves the field according to: ∂L/∂t = -α·ln(L) + D·∇²L
where:
- L(x, y, t): scalar field
- α: nonlinear damping coefficient
- D: diffusion constant
- ∇²L: discrete Laplacian
The equation models a nonlinear parabolic PDE coupling the field’s magnitude to its potential energy, creating self-stabilizing diffusion and entropy-bounded evolution.
