Reproducibility code for "Energy-space quantum walks: Thermalization without state convergence"

This repository provides the reproducibility code for the revised version of the paper "Energy-space quantum walks: Thermalization without state convergence." It contains Python scripts used to reproduce the numerical figures presented in the manuscript. The simulations implement the classical birth-death dynamics in energy space and the corresponding quantum channel, illustrating Gibbs thermalization of the energy populations without, in general, convergence of the full quantum state. Each script reproduces a specific figure and can be executed independently using open-source tools (Python, NumPy, SciPy, and Matplotlib). Pre-generated figures are included for convenience and allow direct inspection of the results without executing the code. The code is self-contained and includes numerical consistency checks to facilitate transparency and reproducibility.
