Thanks for improving your condensed matter problem, but unfortunately further clarifications would be welcome. I know this literature and what you write seems to go against what I know, but before correcting I would like to make sure there is no misunderstanding. What do you mean "not induced by an external stimulus that changes the model parameters"? Any transition is due to some external change of a parameter (temperature or a coupling in the Hamiltonian). 1-d Heisenberg model has only two parameters (nearest neighbor coupling and temperature), so any transition should happen as a function of their ratio. What do you have in mind? Can you tell me which of the two papers you quote posed this problem and where in the paper, so that I can check for myself? (Only problems clearly posed in the research literature have the right to be on this list).
