Thank you @christian512 for reporting this bug! I was aware of it and hoping to fix it as part of #1913. The issue here is that a while ago a...

Hi @pschindler, thanks for reporting this! Although the eigenenstates are different for both cases (`sparse=True` and `sparse=False`) I believe that they are both equally valid since the operator has degenerated...

Hi @pschindler, Indeed, the behavior you show is a bug in qutip 4.7.0. Thanks for reporting this! However, it is actually a bug in the `sparse=True` case. The scipy case...

> Hi @AGaliciaMartinez . Good to hear from you again ;) Hi! :smile: > It seems that the hermitian check for the operator op evaluates as True Yes, this is...

5 seems also fine for me. We default to the dense solver when all the eigenvalues are required, even if `sparse=True` and we then raise a Warning explaining why we...

Thanks for reporting this issue. It does seem to be a bug. I will take a closer look at the `extract_states` method and propose a change.
