Solves the Schrödinger equation with scipy.integrate.ode

Parameters:

  • program (Program) – An analog simulation Hamiltonian for the Rydberg system simulated

  • configurations (list[str]) – The list of configurations that comply with the blockade approximation.

  • simulation_times (list[float]) – The list of time points

  • rydberg_interaction_coef (float) – The interaction coefficient

  • progress_bar (bool) – If true, a progress bar will be printed during the simulation. Default: False

  • atol (float) – Absolute tolerance for solution. Default: 1e-8

  • rtol (float) – Relative tolerance for solution. Default: 1e-6

  • solver_method (str) – Which solver to use, adams for non-stiff problems or bdf for stiff problems. Default: “adams”

  • order (int) – Maximum order used by the integrator, order <= 12 for Adams, <= 5 for BDF. Default: 12

  • nsteps (int) – Maximum number of (internally defined) steps allowed during one call to the solver. Default: 1000

  • first_step (int) – Default: 0

  • max_step (int) – Limits for the step sizes used by the integrator. Default: 0

  • min_step (int) – Default: 0

Returns:

ndarray – The list of all the intermediate states in the simulation.
