Keep running into the problem of "stiff configuration"

When the atoms are too close, the Rydberg interaction can create a large term in the Hamiltonian, making integrating difficult.

In this case, you can try two things:

  1. Set interaction_picture=True option in the solver
  2. Work with the blockade subspace by setting blockade_radius=... to equal the minimum atom spacing.
