There was a wrong factor of /2 in the XY interaction term: what should have been (1 - 3*cos**2) was rather (1 - 3*cos**2) / 2.
This PR:

  • Removes that factor
  • Calculates the cosine with the quantization axis more generically
  • Updates the tutorial using the XY mode to accomodate for the higher interaction strength
