Simulation Scripts---------------------quarter_filling.py Simulates the time evolution of exact eigenstates of the initial Hamiltonian at quarter-filling and calculates the time-dependent pumped charge by integrating the current over time. Parallelized across parameter grids of Hubbard interaction strength (U) and drive frequency (omega). - Data generated for: Figures 2, 9, 10, 11, and 12. extract_J.py Calculates effective spin-exchange couplings at quarter-filling using a three-site cluster.
