Hi Pablo, a few points: You have no Lindblad operators defined, so you cannot expect any decay. The default initial state for the time evolution is the ground state of the Hamiltonian. Then, you evolve under the same Hamiltonian, i.e., you will stay in the eigenstate. The time step you set is taken as-is by OSMPS. A time-step dt=1 is a bit big, especially TDVP will have problems. Suggestions: - Switch off J for the ground state search, your initial state will be a product state of all spins aligned....

Hi Pablo, the quick feedback is: 1) Use TDVP, do not use Krylov. 2) There is no key-value pair in the parameter dictionary for the "QT", see at the end of the function description https://openmps.sourceforge.io/pyautodoc/tools.html?highlight=writefiles#tools.WriteFiles 3) There are no Lindblad operators defined, i.e., we have pure Hamiltonian dynamics. The seed is for each trajectory different and you do not have to run the script multiple time. It is done internally once (2) is set. 4) An MPS with...
