NTC-1 Device Modeling Data: FDTD Configuration Files, Monte Carlo Langevin Solver, and Parameter Sweeps

This repository contains the computational pipeline and raw output arrays required to reproduce the multiphysics modeling of the NTC-1 device architecture. The data flow bridges macroscopic electromagnetic/phononic field modeling (FDTD) to mesoscopic stochastic thermodynamics (Monte Carlo Langevin dynamics). File Architecture Execution Scripts (.py) ntc1_fdtd_meep.py: The open-source Meep (FDTD) configuration script modeling the 20-50 nm pitch phononic silicon waveguides, the CsPbBr3 active layer, and the highly anisotropic hBN encapsulation. langevin_solver.py: The primary Monte Carlo integration script utilizing an Euler-Maruyama scheme to solve the overdamped Langevin equation. Calculates non-Gaussian thermodynamic noise signatures (, ) and estimates mean first-passage times (computational speedup). sweep_fib_depth.py: Sensitivity analysis script modeling the degradation of the localized isotopic spin catalysis as a function of the $^{25}$Mg Focused Ion Beam (FIB) implantation depth variance. generate_figures.py: Production-ready visualization script utilizing Matplotlib/SciPy to generate the schematic and probability density distributions (BGT Metric B) formatted to IEEE publication standards.
