Dear ALPS developers, I have constructed a new model of 1-D interaction fermionic system with disorder and this model works perfectly fun in spectrum function and Lanczos methods. And now I am trying to do the exact solution of time evolution, but it reports "Hamiltonian " type not recognized! use 'Spin'...(whatever exists in models.xml before). Does anyone know how to fix it! Good day!
Hi, I would suggest that you try the new mps codes, which are more flexible regarding the models. Michele Dolfi can help if you have questions Matthias

Thank you Matthias, I am not familiar with MPS but I will try. But do you know why the the group '/timesteps' was not passed to the funtion "loadTimeEvolution"? plus, All the others models have not defined anything to do with time evolution. best 2015-05-22 17:36 GMT+02:00 Matthias Troyer <troyer@phys.ethz.ch>:

You will need to wait for answers from the authors of that code, since I don’t understand your question

Hello, The TEBD code only works with the spin, hardcore boson, spinless fermion, boson Hubbard, and fermion Hubbard models from the ALPS models library. The parameters in these models can be made time-dependent, which is where the dynamics comes from. If you are using a different model, the mps codes are more appropriate, as Matthias suggests. -Michael On Fri, May 22, 2015 at 10:22 AM, Cathy Wu <cathy.em2013@gmail.com> wrote:

BTW, I want to use cos function in my Hamiltonian in models.xml, it seems that it does not interpret that. But it Interprets cos function in lattice.xml. How can I make it work??? help! good day! 2015-05-26 22:44 GMT+02:00 Cathy Wu <cathy.em2013@gmail.com>:
